Implement smart Magic DNS copy with automatic port detection

### Magic DNS Smart Copy Features:
- **PBS servers**: Automatically append `:8007` port when copying
- **PVE servers**: Automatically append `:8006` port when copying
- **Other machines**: Copy Magic DNS address without port (existing behavior)

### UI Improvements:
- PBS servers: Blue button with `:8007` port hint
- PVE servers: Orange button with `:8006` port hint
- Enhanced tooltips with service-specific port information
- Visual distinction between different server types

### PBS Backup Server Monitoring:
- Complete PBS API integration with authentication
- Real-time backup/restore task monitoring with detailed logs
- Namespace-separated backup visualization with color coding
- Datastore usage monitoring and status tracking
- Task history with success/failure status and error details

### Technical Implementation:
- Smart port detection via JavaScript `addSmartPort()` function
- Jinja2 template logic for conditional button styling
- PBS API endpoints for comprehensive backup monitoring
- Enhanced clipboard functionality with user feedback
