feat: add Koa2 BFF server, CLI management, sessions CLI integration, and logs page

- Add Koa2 BFF layer for API proxy, file upload, session management
- Auto-check and enable api_server in ~/.hermes/config.yaml on startup
- Integrate sessions with Hermes CLI (list, get, delete)
- Add Logs page with level filtering, log file selection, and search
- Add CLI commands: start/stop/restart/status for daemon management
- Unify package.json for frontend and server dependencies
- Default port changed to 8648
