fix(keycloak): update user club attributes with real database UUIDs

- Replaced placeholder UUIDs (club-1-uuid, club-2-uuid) with real database UUIDs
- Updated all 5 test users via Keycloak database
- Restarted Keycloak to clear caches and apply changes

Impact:
- JWT tokens now contain real UUIDs in clubs claim
- API endpoints accept X-Tenant-Id with real UUIDs (returns 200 OK)
- Unblocks 46 remaining QA scenarios

Documentation:
- Created update-keycloak-club-uuids.py script for automation
- Added KEYCLOAK_UPDATE_GUIDE.md with step-by-step instructions
- Recorded learnings in notepad
