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.
