Move TTS server status from frontend to admin dashboard

- Removed TTS server status popup from main frontend interface
- Commented out checkTtsServer() function and all its calls
- Removed TTS configuration UI elements from index.html
- Added comprehensive TTS server monitoring to admin dashboard:
  - Configuration status (URL, API key)
  - Server health monitoring
  - Available voices display
  - Usage statistics and performance metrics
  - Real-time status updates
- Enhanced system health check to include TTS server
- Created dedicated /api/tts/status endpoint for detailed info

The TTS functionality remains fully operational for users, but status
monitoring is now exclusive to the admin dashboard for cleaner UX.
