BLOG-85 refactor: enhance configuration management with database, server, session, and storage modules

- Added OIDC authentication support with new modules for handling OIDC login and callback.
- Introduced `AuthController`, `AuthOidcService`, and related DTOs for managing authentication state and user responses.
- Implemented session management using `actix-session` with Redis for storing authentication state.
- Created configuration management for OIDC settings, including provider metadata and client credentials.
- Updated server configuration to initialize OIDC services and session management.
- Refactored existing code to integrate new authentication features and ensure proper dependency management.
