1cf0ef0d9c feat(backend): Implement password reset flow (Phase 3)
Complete implementation of secure password reset functionality per DAY7-PRD.md specifications.

Changes:
- Domain: PasswordResetToken entity with 1-hour expiration and single-use constraint
- Domain Events: PasswordResetRequestedEvent and PasswordResetCompletedEvent
- Repository: IPasswordResetTokenRepository with token management and invalidation
- Commands: ForgotPasswordCommand and ResetPasswordCommand with handlers
- Security: MemoryRateLimitService (3 requests/hour) and IRateLimitService interface
- API: POST /api/Auth/forgot-password and POST /api/Auth/reset-password endpoints
- Infrastructure: EF Core configuration and database migration for password_reset_tokens table
- Features: Email enumeration prevention, SHA-256 token hashing, refresh token revocation on password reset
- Test: PowerShell test script for password reset flow verification

Security Enhancements:
- Rate limiting: 3 forgot-password requests per hour per email
- Token security: SHA-256 hashing, 1-hour expiration, single-use only
- Privacy: Always return success message to prevent email enumeration
- Audit trail: IP address and User Agent logging for security monitoring
- Session revocation: All refresh tokens revoked after successful password reset

Database:
- New table: password_reset_tokens with indexes for performance
- Columns: id, user_id, token_hash, expires_at, used_at, ip_address, user_agent, created_at

ebdd4ee0d7 fix(backend): Fix Integration Test database provider conflict with environment-aware DI
Implement environment-aware dependency injection to resolve EF Core provider conflict
in Integration Tests. The issue was caused by both PostgreSQL and InMemory providers
being registered in the same service provider.

Changes:
- Modified Identity Module DependencyInjection to skip PostgreSQL DbContext registration in Testing environment
- Modified ProjectManagement Module ModuleExtensions with same environment check
- Updated Program.cs to pass IHostEnvironment to both module registration methods
- Added Microsoft.Extensions.Hosting.Abstractions package to Identity.Infrastructure project
- Updated ColaFlowWebApplicationFactory to set Testing environment and register InMemory databases
- Simplified WebApplicationFactory by removing complex RemoveAll logic

Results:
- All 31 Integration Tests now run (previously only 1 ran)
- No EF Core provider conflict errors
- 23 tests pass, 8 tests fail (failures are business logic issues, not infrastructure)
- Production environment still uses PostgreSQL as expected

aaab26ba6c feat(backend): Implement complete RBAC system (Day 5 Phase 2)
Implemented Role-Based Access Control (RBAC) with 5 tenant-level roles following Clean Architecture principles.

Changes:
- Created TenantRole enum (TenantOwner, TenantAdmin, TenantMember, TenantGuest, AIAgent)
- Created UserTenantRole entity with repository pattern
- Updated JWT service to include role claims (tenant_role, role)
- Updated RegisterTenant to auto-assign TenantOwner role
- Updated Login to query and include user role in JWT
- Updated RefreshToken to preserve role claims
- Added authorization policies in Program.cs (RequireTenantOwner, RequireTenantAdmin, etc.)
- Updated /api/auth/me endpoint to return role information
- Created EF Core migration for user_tenant_roles table
- Applied database migration successfully

Database:
- New table: identity.user_tenant_roles
- Columns: id, user_id, tenant_id, role, assigned_at, assigned_by_user_id
- Indexes: user_id, tenant_id, role, unique(user_id, tenant_id)
- Foreign keys: CASCADE on user and tenant deletion

Testing:
- Created test-rbac.ps1 PowerShell script
- All RBAC tests passing
- JWT tokens contain role claims
- Role persists across login and token refresh

Documentation:
- DAY5-PHASE2-RBAC-IMPLEMENTATION-SUMMARY.md with complete implementation details
