feat: Enhance frontend loading experience and service status handling

### Summary of Changes
- Removed proxy configuration in `rsbuild.config.js` as the API Gateway is not running.
- Added smooth transitions and gentle loading overlays in CSS for improved user experience during data loading.
- Updated `Dashboard` component to conditionally display loading spinner and gentle loading overlay based on data fetching state.
- Enhanced `useOfflineAwareServiceStatus` and `useOfflineAwareSystemData` hooks to manage loading states and service status more effectively.
- Increased refresh intervals for service status and system data to reduce API call frequency.

### Expected Results
- Improved user experience with smoother loading transitions and better feedback during data refreshes.
- Enhanced handling of service status checks, providing clearer information when services are unavailable.
- Streamlined code for managing loading states, making it easier to maintain and extend in the future.

+# Health Checking System
+
+This document describes the generalized health checking system for LabFusion Service Adapters.
+
+## Overview
+
+The health checking system is designed to be flexible and extensible, supporting different types of health checks for different services. It uses a strategy pattern with pluggable health checkers.
+
+## Architecture
+
+### Core Components
+
+1. **BaseHealthChecker**: Abstract base class for all health checkers
+2. **HealthCheckResult**: Standardized result object
+3. **HealthCheckerRegistry**: Registry for different checker types
+4. **HealthCheckerFactory**: Factory for creating checker instances
+5. **ServiceStatusChecker**: Main orchestrator
+
+### Health Checker Types
+
+#### 1. API Health Checker (`APIHealthChecker`)
+- **Purpose**: Check services with HTTP health endpoints
+- **Use Case**: Most REST APIs, microservices
+- **Configuration**:
+  ```python
+  {
+      "health_check_type": "api",
+      "health_endpoint": "/api/health",
+      "url": "https://service.example.com"
+  }
+  ```
+
+#### 2. Sensor Health Checker (`SensorHealthChecker`)
+- **Purpose**: Check services via sensor data (e.g., Home Assistant entities)
+- **Use Case**: Home Assistant, IoT devices, sensor-based monitoring
+- **Configuration**:
+  ```python
+  {
+      "health_check_type": "sensor",
+      "sensor_entity": "sensor.system_uptime",
+      "url": "https://homeassistant.example.com"
+  }
+  ```
+
+#### 3. Custom Health Checker (`CustomHealthChecker`)
+- **Purpose**: Complex health checks with multiple validation steps
+- **Use Case**: Services requiring multiple checks, custom logic
+- **Configuration**:
+  ```python
+  {
+      "health_check_type": "custom",
+      "health_checks": [
+          {
+              "type": "api",
+              "name": "main_api",
+              "url": "https://service.example.com/api/health"
+          },
+          {
+              "type": "sensor",
+              "name": "uptime_sensor",
+              "sensor_entity": "sensor.service_uptime"
+          }
+      ]
+  }
+  ```
+
+## Configuration
+
+### Service Configuration Structure
+
+```python
+SERVICES = {
+    "service_name": {
+        "url": "https://service.example.com",
+        "enabled": True,
+        "health_check_type": "api|sensor|custom",
+        
+        # API-specific
+        "health_endpoint": "/api/health",
+        "token": "auth_token",
+        "api_key": "api_key",
+        
+        # Sensor-specific
+        "sensor_entity": "sensor.entity_name",
+        
+        # Custom-specific
+        "health_checks": [
+            {
+                "type": "api",
+                "name": "check_name",
+                "url": "https://endpoint.com/health"
+            }
+        ]
+    }
+}
+```
+
+### Environment Variables
+
+```bash
+# Service URLs
+HOME_ASSISTANT_URL=https://ha.example.com
+FRIGATE_URL=http://frigate.local:5000
+IMMICH_URL=http://immich.local:2283
+N8N_URL=http://n8n.local:5678
+
+# Authentication
+HOME_ASSISTANT_TOKEN=your_token
+FRIGATE_TOKEN=your_token
+IMMICH_API_KEY=your_key
+N8N_API_KEY=your_key
+```
+
+## Usage Examples
+
+### Basic API Health Check
+
+```python
+from services.health_checkers import factory
+
+# Create API checker
+checker = factory.create_checker("api", timeout=5.0)
+
+# Check service
+config = {
+    "url": "https://api.example.com",
+    "health_endpoint": "/health",
+    "enabled": True
+}
+result = await checker.check_health("example_service", config)
+print(f"Status: {result.status}")
+print(f"Response time: {result.response_time}s")
+```
+
+### Sensor-Based Health Check
+
+```python
+# Create sensor checker
+checker = factory.create_checker("sensor", timeout=5.0)
+
+# Check Home Assistant sensor
+config = {
+    "url": "https://ha.example.com",
+    "sensor_entity": "sensor.system_uptime",
+    "token": "your_token",
+    "enabled": True
+}
+result = await checker.check_health("home_assistant", config)
+print(f"Uptime: {result.metadata.get('sensor_state')}")
+```
+
+### Custom Health Check
+
+```python
+# Create custom checker
+checker = factory.create_checker("custom", timeout=10.0)
+
+# Check with multiple validations
+config = {
+    "url": "https://service.example.com",
+    "enabled": True,
+    "health_checks": [
+        {
+            "type": "api",
+            "name": "main_api",
+            "url": "https://service.example.com/api/health"
+        },
+        {
+            "type": "api",
+            "name": "database",
+            "url": "https://service.example.com/api/db/health"
+        }
+    ]
+}
+result = await checker.check_health("complex_service", config)
+print(f"Overall status: {result.status}")
+print(f"Individual checks: {result.metadata.get('check_results')}")
+```
+
+## Health Check Results
+
+### HealthCheckResult Structure
+
+```python
+{
+    "status": "healthy|unhealthy|disabled|error|timeout|unauthorized|forbidden",
+    "response_time": 0.123,  # seconds
+    "error": "Error message if applicable",
+    "metadata": {
+        "http_status": 200,
+        "response_size": 1024,
+        "sensor_state": "12345",
+        "last_updated": "2024-01-15T10:30:00Z"
+    }
+}
+```
+
+### Status Values
+
+- **healthy**: Service is responding normally
+- **unhealthy**: Service responded but with error status
+- **disabled**: Service is disabled in configuration
+- **timeout**: Request timed out
+- **unauthorized**: Authentication required (HTTP 401)
+- **forbidden**: Access forbidden (HTTP 403)
+- **error**: Network or other error occurred
+
+## Extending the System
+
+### Adding a New Health Checker
+
+1. **Create the checker class**:
+   ```python
+   from .base import BaseHealthChecker, HealthCheckResult
+   
+   class MyCustomChecker(BaseHealthChecker):
+       async def check_health(self, service_name: str, config: Dict) -> HealthCheckResult:
+           # Implementation
+           pass
+   ```
+
+2. **Register the checker**:
+   ```python
+   from services.health_checkers import registry
+   
+   registry.register("my_custom", MyCustomChecker)
+   ```
+
+3. **Use in configuration**:
+   ```python
+   {
+       "health_check_type": "my_custom",
+       "custom_param": "value"
+   }
+   ```
+
+### Service-Specific Logic
+
+The factory automatically selects the appropriate checker based on:
+1. `health_check_type` in configuration
+2. Service name patterns
+3. Configuration presence (e.g., `sensor_entity` → sensor checker)
+
+## Performance Considerations
+
+- **Concurrent Checking**: All services are checked simultaneously
+- **Checker Caching**: Checkers are cached per service to avoid recreation
+- **Timeout Management**: Configurable timeouts per checker type
+- **Resource Cleanup**: Proper cleanup of HTTP clients
+
+## Monitoring and Logging
+
+- **Debug Logs**: Detailed operation logs for troubleshooting
+- **Performance Metrics**: Response times and success rates
+- **Error Tracking**: Comprehensive error logging with context
+- **Health Summary**: Overall system health statistics
+
+## Best Practices
+
+1. **Choose Appropriate Checker**: Use the right checker type for your service
+2. **Set Reasonable Timeouts**: Balance responsiveness with reliability
+3. **Handle Errors Gracefully**: Always provide meaningful error messages
+4. **Monitor Performance**: Track response times and success rates
+5. **Test Thoroughly**: Verify health checks work in all scenarios
+6. **Document Configuration**: Keep service configurations well-documented
+
+## Troubleshooting
+
+### Common Issues
+
+1. **Timeout Errors**: Increase timeout or check network connectivity
+2. **Authentication Failures**: Verify tokens and API keys
+3. **Sensor Not Found**: Check entity names and permissions
+4. **Configuration Errors**: Validate service configuration structure
+
+### Debug Tools
+
+- **Debug Endpoint**: `/debug/logging` to test logging configuration
+- **Health Check Logs**: Detailed logs for each health check operation
+- **Metadata Inspection**: Check metadata for additional context

+# Unified Logging Configuration
+
+This document describes the unified logging setup and usage in the LabFusion Service Adapters.
+
+## Overview
+
+The service adapters use Python's built-in `logging` module with a centralized configuration system that provides **unified logging for both application logs and incoming request logs**. All logs use the same format, handler, and configuration for consistency and easier monitoring.
+
+## Logging Levels
+
+- **DEBUG**: Detailed information for debugging (status checker operations)
+- **INFO**: General information about application flow
+- **WARNING**: Warning messages for non-critical issues
+- **ERROR**: Error messages for failed operations
+- **CRITICAL**: Critical errors that may cause application failure
+
+## Configuration
+
+Logging is configured in `services/logging_config.py` with unified settings:
+
+- **Root Level**: INFO
+- **Status Checker**: DEBUG (detailed health check logging)
+- **Routes**: INFO (API endpoint logging)
+- **Request Logging**: INFO (unified with application logs)
+- **HTTP Client**: WARNING (reduced verbosity)
+- **Unified Handler**: Single handler for all log types
+
+## Log Format
+
+**Unified Format** (same for application and request logs):
+```
+2024-01-15 10:30:45,123 - services.status_checker - INFO - status_checker.py:140 - Starting health check for 4 services
+2024-01-15 10:30:45,124 - uvicorn.access - INFO - logging_middleware.py:45 - Request started: GET /services from 192.168.1.100
+2024-01-15 10:30:45,125 - routes.general - INFO - general.py:78 - Service status endpoint called - checking all services
+2024-01-15 10:30:45,126 - uvicorn.access - INFO - logging_middleware.py:55 - Request completed: GET /services -> 200 in 0.123s
+```
+
+Format includes:
+- Timestamp
+- Logger name (unified across all log types)
+- Log level
+- Filename and line number
+- Message
+
+## Usage Examples
+
+### Basic Logging
+```python
+import logging
+from services.logging_config import get_logger
+
+logger = get_logger(__name__)
+
+logger.debug("Debug information")
+logger.info("General information")
+logger.warning("Warning message")
+logger.error("Error occurred")
+```
+
+### Request Logging
+```python
+from services.logging_config import get_request_logger
+
+request_logger = get_request_logger()
+request_logger.info("Custom request log message")
+```
+
+### Application Logging
+```python
+from services.logging_config import get_application_logger
+
+app_logger = get_application_logger()
+app_logger.info("Application-level log message")
+```
+
+### Service Status Logging
+The status checker automatically logs:
+- Health check start/completion
+- Individual service responses
+- Response times
+- Error conditions
+- Authentication status
+
+### API Endpoint Logging
+Routes log:
+- Endpoint calls
+- Request processing
+- Response generation
+
+### Request Middleware Logging
+The logging middleware automatically logs:
+- Request start (method, path, client IP, user agent)
+- Request completion (status code, processing time)
+- Request errors (exceptions, processing time)
+
+## Debug Endpoint
+
+A debug endpoint is available at `/debug/logging` to:
+- Test unified log levels across all logger types
+- View current configuration
+- Verify unified logging setup
+- Test request, application, and route loggers
+
+## Environment Variables
+
+You can control logging behavior with environment variables:
+
+```bash
+# Set log level (DEBUG, INFO, WARNING, ERROR, CRITICAL)
+export LOG_LEVEL=DEBUG
+
+# Disable timestamps
+export LOG_NO_TIMESTAMP=true
+```
+
+## Log Files
+
+Currently, logs are output to stdout. For production, consider:
+- File logging with rotation
+- Structured logging (JSON)
+- Log aggregation (ELK stack, Fluentd)
+- Log levels per environment
+
+## Troubleshooting
+
+### No Logs Appearing
+1. Check log level configuration
+2. Verify logger names match module names
+3. Ensure logging is initialized before use
+
+### Too Many Logs
+1. Increase log level to WARNING or ERROR
+2. Disable DEBUG logging for specific modules
+3. Use log filtering
+
+### Performance Impact
+1. Use appropriate log levels
+2. Avoid logging in tight loops
+3. Consider async logging for high-volume applications
+
+## Best Practices
+
+1. **Use appropriate levels**: DEBUG for development, INFO for production
+2. **Include context**: Service names, request IDs, user information
+3. **Structured messages**: Consistent format for parsing
+4. **Avoid sensitive data**: No passwords, tokens, or personal information
+5. **Performance**: Log asynchronously when possible
+6. **Monitoring**: Set up alerts for ERROR and CRITICAL levels
