[EDIFIKANA] #424 Common Area API contracts and backend services

[gaaliciA1990]

Summary

Closes #424

• Adds full backend stack for Common Areas: API definition, domain model, datastore interface + Supabase implementation, service, controller, RBAC support, and DI registrations
• Fixes type field in shared network models (CommonAreaNetworkResponse, CreateCommonAreaNetworkRequest, UpdateCommonAreaNetworkRequest) from raw String to CommonAreaType
• Adds full test coverage: unit tests (CommonAreaServiceTest, CommonAreaControllerTest) and integration tests (SupabaseCommonAreaDatastoreIntegrationTest, 8/8 passing)

Test plan

• ./gradlew :edifikana:back-end:test — all unit tests pass
• ./gradlew :edifikana:back-end:integTest — all 8 integration tests pass against live Supabase
• ./gradlew releaseAll — full build passes with no errors
