Refactor routing and documentation for SPA deployment

- Updated the application to serve the SPA from the root path instead of /map/, enhancing accessibility.
- Modified redirect logic to ensure backward compatibility with old /map/* URLs.
- Adjusted documentation across multiple files to reflect the new routing structure and API endpoints.
- Improved handling of OAuth redirects and session management in the backend.
- Updated frontend configuration to align with the new base URL settings.
