feat: enhance authentication and session management

- Added NODE_ENV variable for development in docker-compose.override.yml.example.
- Changed default NODE_ENV to development in Dockerfile.
- Implemented fetchWsToken function to retrieve short-lived WebSocket tokens for secure authentication in TerminalPanel.
- Updated connect function to use wsToken for WebSocket connections when API key is not available.
- Introduced verifySession function to validate session status after login and on app load, ensuring session integrity.
- Modified RootLayoutContent to verify session cookie validity and redirect to login if the session is invalid or expired.

These changes improve the security and reliability of the authentication process.
