Implement improved auto-reconnect logic and fix TypeScript errors

## Features
- Add proactive health check monitoring for MCP connections (30s intervals)
- Implement automatic reconnection on health check failures
- Add proper cleanup of health check intervals on disconnect

## Fixes
- Resolve OAuth type compatibility issues with MCP SDK
- Fix naming collision between InferenceProvider class and React component
- Remove unused React imports across all components (new JSX transform)
- Clean up unused type imports and variables
- Remove unused handleOAuthAuthentication function

## Technical Details
- Health checks use lightweight listTools() calls to verify connection state
- Automatic reconnection triggers when health checks fail
- Maintains existing exponential backoff retry logic
- All TypeScript compilation errors resolved
