Integrate draft session support with phase handling and real-time updates

- Added user authentication UI in the base template for navbar.
- Expanded `league.dj.html` to include a new "Draft Sessions" tab showing active drafts.
- Refactored Django views and models to support `DraftSession` with participants and movies.
- Replaced deprecated models like `DraftParticipant` and `DraftMoviePool` with a new schema using `DraftSessionParticipant`.
- Introduced WebSocket consumers (`DraftAdminConsumer`, `DraftParticipantConsumer`) with structured phase logic and caching.
- Added `DraftStateManager` for managing draft state in Django cache.
- Created frontend UI components in React for draft admin and participants, including phase control and WebSocket message logging.
- Updated SCSS styles for improved UI structure and messaging area.
