Subject: [PATCH] feat: Complete remaining management pages (Applications,
 Articles, Monitoring)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Frontend Implementation:
- Applications page: OAuth app management with client ID/secret
  * Client secret regeneration with secure display
  * Redirect URI management with chip interface
  * Copy-to-clipboard for credentials

- Articles page: News articles browser with filters
  * Category, translation, and image status filters
  * Article detail modal with full content
  * Retry controls for failed translations/images
  * Server-side pagination support

- Monitoring page: System health and metrics dashboard
  * Real-time CPU, memory, and disk usage
  * Database statistics display
  * Services status monitoring
  * Recent logs table with level filtering
  * Auto-refresh toggle (30s interval)

All pages follow the established DataGrid + MainLayout pattern with:
- Consistent UI/UX across all management pages
- Material-UI components and styling
- Error handling and loading states
- Full API integration with backend endpoints
