Update OAuth redirect URIs and API routing structure

- Changed the Google and Apple redirect URIs in the configuration to include the API version in the path.
- Reorganized the inclusion of OAuth routes in the main application to ensure they are properly prefixed and accessible.

These updates aim to enhance the API structure and ensure consistency in the authentication flow.
