Refactor draft messaging to unified enum-based protocol

Browse Source 
- Replaced scattered message strings with `DraftMessage` `StrEnum` and
  numeric `DraftPhase` `IntEnum` for clear, centralized definitions.
- Added Python→JS constants sync via `scripts/generate_js_constants.py`
  to ensure backend/frontend parity.
- Refactored WebSocket consumers to use `broadcast.*` and
  `direct.message` handlers with `_dispatch_broadcast` for consistent
  event delivery.
- Enhanced `DraftStateManager` to store `draft_index` and explicitly
  manage `connected_participants`.
- Added colored logging config in settings for improved debugging.
- Frontend: split UI into `ParticipantList` and `DraftMoviePool`,
  extracted message handlers (`handleDraftStatusMessages`,
  `handleUserIdentifyMessages`), and updated components to use new
  message/phase enums.
