Database schema initialized with:
- 10 ENUM types
- 17 tables (users, events, subscriptions, donations, RBAC, documents, system)
- 30+ indexes for performance
- 1 storage usage record

Next steps:
1. Run: python seed_permissions_rbac.py  (to populate permissions and roles)
2. Run: python create_admin.py           (to create superadmin user)
3. Run remaining migrations in sequence  (001-010)

Database is ready for LOAF membership platform! 🎉
