Create fresh NpgsqlConnection per tenant iteration instead of reusing
EF Core's managed connection. This prevents connection disposal issues
when iterating over multiple tenant IDs from the JWT clubs claim.
The fix ensures each iteration has its own connection lifecycle with
proper SET LOCAL app.current_tenant_id for RLS compliance.
Implement Task 16: Club + Member API endpoints with MemberSyncService
Services:
- ClubService: GetMyClubsAsync (user's clubs), GetCurrentClubAsync (tenant club)
- MemberService: GetMembersAsync (list), GetMemberByIdAsync, GetCurrentMemberAsync
- MemberSyncService: Auto-creates Member records from JWT on first request
Middleware:
- MemberSyncMiddleware: Runs after auth, calls MemberSyncService
Endpoints:
- GET /api/clubs/me (list user's clubs)
- GET /api/clubs/current (current tenant's club)
- GET /api/members (list members, RLS filtered)
- GET /api/members/{id} (member detail)
- GET /api/members/me (current user's membership)
Tests: 14 integration tests (6 club + 8 member)
- Club filtering by user membership
- Multi-tenant isolation via RLS
- Member auto-sync on first request
- Cross-tenant access blocked
- Role-based authorization
Build: 0 errors, all tests compile
Pattern: TypedResults, RequireAuthorization policies, TDD approach
