Enhance user login and team configuration management

- Updated login configuration tests to clarify endpoint descriptions.
- Introduced team configuration loading and retrieval functionality, including new endpoints for public access to team configurations.
- Refactored team management routes to standardize parameter usage and improve clarity.
- Added error handling for missing environment variables in client configuration.
- Implemented team configuration types and related structures for better organization and usability.
