Simplify MCP connection handling and remove health checks

- Remove auth type selection from UI - servers will auto-detect OAuth when needed
- Remove auto-reconnect logic and health checks to reduce complexity
- Always initialize OAuth provider for all connections
- Simplify transport selection - always try streamable-http first, then SSE
- Remove unused config options (transport preference, auto-reconnect)
- Add TODO comment about CORS issues for failed fetch errors
- Make authType and transport optional in connection types
- Clean up connection state notifications for better UI updates
