- Replace UserTypes with barangay roles (super_admin, punong_barangay,
  kagawad, secretary, treasurer, sk_chairperson, sk_councilor, tanod,
  bhw, daycare_worker, staff, resident, audit)
- Replace UserActions with barangay-specific permissions (residents,
  households, blotters, documents, fee payments, projects, budget)
- Replace modules config with barangay modules (residents, households,
  blotters, documents, certificates, projects, budget, announcements,
  accounting, chapters, qr_payment, subscriptions, landing_pages)
- Update app name, seeders, and landing page to barangay defaults
- Add new enums: DocumentStatus, BlotterStatus, PaymentStatus
- Add 6 new migrations: residents, households, blotters, document
  requests, projects, budget
- Add RequestTypeSeeder with default certificate fee schedule
- Update README with BarangaySystem stack, roles, and remotes
