feat: Integrate SonarQube analysis into CI workflows

### Summary of Changes
- Added SonarQube analysis steps to all CI workflows (API Docs, API Gateway, Frontend, Service Adapters).
- Configured SonarQube properties for each service to ensure proper reporting and analysis.
- Enhanced test coverage reporting by specifying multiple coverage reporters in test commands.
- Updated Maven and Python dependencies to include SonarQube integration tools.

### Expected Results
- CI pipelines will now send test and coverage results to SonarQube for better quality tracking.
- Improved visibility into code quality and test coverage across all services.

+# SonarQube Integration for LabFusion
+
+This document explains how to configure SonarQube integration for all LabFusion services in a unified project.
+
+## Overview
+
+All LabFusion services (API Gateway, Service Adapters, API Docs, Frontend) now send test results, code coverage, and quality metrics directly to a single unified SonarQube project called "LabFusion" instead of using external test reporters.
+
+## Required Configuration
+
+### 1. SonarQube Secrets
+
+You need to configure the following secrets in your Gitea repository:
+
+- `SONAR_HOST_URL`: Your SonarQube server URL (e.g., `http://localhost:9000` or `https://sonar.yourdomain.com`)
+- `SONAR_TOKEN`: Your SonarQube authentication token
+
+### 2. SonarQube Project Setup
+
+1. **Create a unified project** in SonarQube:
+   - Project Key: `labfusion`
+   - Project Name: `LabFusion`
+   - Main Branch: `main`
+
+2. **Generate an authentication token**:
+   - Go to User > My Account > Security
+   - Generate a new token with appropriate permissions
+   - Copy the token for use in `SONAR_TOKEN` secret
+
+### 3. SonarQube Quality Gates
+
+Configure quality gates in SonarQube to enforce:
+- Minimum code coverage percentage
+- Maximum code duplication percentage
+- Maximum technical debt ratio
+- Code smell thresholds
+
+## What Gets Sent to SonarQube
+
+### Unified LabFusion Project Structure
+- **Project Key**: `labfusion`
+- **Project Name**: `LabFusion`
+- **Modules**:
+  - `api-gateway` (Java Spring Boot)
+  - `service-adapters` (Python FastAPI)
+  - `api-docs` (Node.js Express)
+  - `frontend` (React)
+
+### Test Results
+- **API Gateway**: JUnit XML reports from `target/surefire-reports/`
+- **Service Adapters**: pytest XML reports from `tests/reports/junit.xml`
+- **API Docs**: Jest XML reports from `test-results.xml`
+- **Frontend**: Jest XML reports from `test-results.xml`
+
+### Code Coverage
+- **API Gateway**: JaCoCo XML report from `target/site/jacoco/jacoco.xml`
+- **Service Adapters**: Coverage XML from `coverage.xml`
+- **API Docs**: LCOV report from `coverage/lcov.info`
+- **Frontend**: LCOV report from `coverage/lcov.info`
+
+### Code Quality Metrics
+- **Source code analysis** results for all languages
+- **Code smells** and issues across all services
+- **Security vulnerabilities** detection
+- **Maintainability ratings** per module
+
+## Pipeline Integration
+
+### All Services Send to Unified Project
+Each service workflow includes a SonarQube integration step:
+
+#### API Gateway (Java)
+```yaml
+- name: Send test results to SonarQube
+  run: |
+    ./mvnw sonar:sonar \
+      -Dsonar.projectKey=labfusion \
+      -Dsonar.modules=api-gateway \
+      # ... other properties
+```
+
+#### Service Adapters (Python)
+```yaml
+- name: Send results to SonarQube
+  run: |
+    sonar-scanner \
+      -Dsonar.projectKey=labfusion \
+      -Dsonar.modules=service-adapters \
+      # ... other properties
+```
+
+#### API Docs & Frontend (Node.js)
+```yaml
+- name: Send results to SonarQube
+  run: |
+    sonar-scanner \
+      -Dsonar.projectKey=labfusion \
+      -Dsonar.modules=api-docs \
+      # ... other properties
+```
+
+## Maven Plugins Added
+
+### SonarQube Maven Plugin
+```xml
+<plugin>
+    <groupId>org.sonarsource.scanner.maven</groupId>
+    <artifactId>sonar-maven-plugin</artifactId>
+    <version>3.10.0.2594</version>
+</plugin>
+```
+
+### JaCoCo Maven Plugin
+```xml
+<plugin>
+    <groupId>org.jacoco</groupId>
+    <artifactId>jacoco-maven-plugin</artifactId>
+    <version>0.8.11</version>
+    <!-- Configured for test phase execution -->
+</plugin>
+```
+
+## SonarQube Properties
+
+Each service generates its own `sonar-project.properties` with module-specific settings:
+
+### API Gateway
+```properties
+sonar.projectKey=labfusion
+sonar.projectName=LabFusion
+sonar.projectVersion=1.0.0
+sonar.modules=api-gateway
+sonar.sources=src/main/java
+sonar.tests=src/test/java
+sonar.java.binaries=target/classes
+sonar.java.test.binaries=target/test-classes
+sonar.junit.reportPaths=target/surefire-reports
+sonar.coverage.jacoco.xmlReportPaths=target/site/jacoco/jacoco.xml
+```
+
+### Service Adapters
+```properties
+sonar.projectKey=labfusion
+sonar.projectName=LabFusion
+sonar.projectVersion=1.0.0
+sonar.modules=service-adapters
+sonar.sources=.
+sonar.tests=tests
+sonar.python.coverage.reportPaths=coverage.xml
+sonar.python.xunit.reportPath=tests/reports/junit.xml
+```
+
+### API Docs & Frontend
+```properties
+sonar.projectKey=labfusion
+sonar.projectName=LabFusion
+sonar.projectVersion=1.0.0
+sonar.modules=api-docs
+sonar.sources=.
+sonar.tests=__tests__
+sonar.javascript.lcov.reportPaths=coverage/lcov.info
+sonar.testExecutionReportPaths=test-results.xml
+```
+
+## Benefits
+
+### 1. Centralized Quality Management
+- All quality metrics in one place
+- Historical trend analysis
+- Cross-project comparisons
+
+### 2. Automated Quality Gates
+- Pipeline fails if quality standards not met
+- Enforces consistent code quality
+- Prevents regression in code quality
+
+### 3. Detailed Reporting
+- Comprehensive test coverage reports
+- Code smell identification
+- Security vulnerability detection
+- Technical debt tracking
+
+### 4. Integration Benefits
+- No external service dependencies
+- Local data control
+- Customizable quality rules
+- Team collaboration features
+
+## Troubleshooting
+
+### Common Issues
+
+1. **Authentication Failed**
+   - Verify `SONAR_TOKEN` is correct
+   - Check token permissions in SonarQube
+   - Ensure token hasn't expired
+
+2. **Connection Refused**
+   - Verify `SONAR_HOST_URL` is accessible
+   - Check network connectivity
+   - Ensure SonarQube is running
+
+3. **Project Not Found**
+   - Create project in SonarQube first
+   - Verify project key matches configuration
+   - Check project permissions
+
+4. **No Test Results**
+   - Ensure test files exist in `src/test/java/`
+   - Verify Maven Surefire plugin configuration
+   - Check test execution logs
+
+### Debug Commands
+
+```bash
+# Test SonarQube connection
+curl -u $SONAR_TOKEN: $SONAR_HOST_URL/api/system/status
+
+# Check project exists
+curl -u $SONAR_TOKEN: $SONAR_HOST_URL/api/projects/search?q=labfusion-api-gateway
+
+# Verify test reports exist
+ls -la target/surefire-reports/
+ls -la target/site/jacoco/
+```
+
+## Next Steps
+
+1. **Configure SonarQube secrets** in your Gitea repository
+2. **Set up quality gates** in SonarQube
+3. **Run the pipeline** to test integration
+4. **Review results** in SonarQube dashboard
+5. **Customize quality rules** as needed
