ajaysi 49e0ee8e9e Consolidate on ALWRITY_ENABLED_FEATURES - remove all legacy support
Backend:
- Remove all legacy env var fallbacks (ALWRITY_FEATURE_PROFILE, ALWRITY_ROUTER_PROFILE, etc)
- Remove get_active_profile() from start_alwrity_backend.py
- Remove _env_flag_enabled() from app.py
- Use ALWRITY_ENABLED_FEATURES as single source of truth

Frontend:
- demoMode.ts now uses only REACT_APP_ENABLED_FEATURES
- Removed all legacy fallback keys (app_mode, demo_mode, podcast_only_demo_mode)

Usage:
  ALWRITY_ENABLED_FEATURES=podcast     # Podcast only
  ALWRITY_ENABLED_FEATURES=all        # All features (default)
