Rename Forte to LunarFront, generalize for any small business

Rebrand from Forte (music-store-specific) to LunarFront (any small business):
- Package namespace @forte/* → @lunarfront/*
- Database forte/forte_test → lunarfront/lunarfront_test
- Docker containers, volumes, connection strings
- UI branding, localStorage keys, test emails
- All documentation and planning docs

Generalize music-specific terminology:
- instrumentDescription → itemDescription
- instrumentCount → itemCount
- instrumentType → itemCategory (on service templates)
- New migration 0027_generalize_terminology for column renames
- Seed data updated with generic examples
- RBAC descriptions updated
