feat(wbs): AEG-VS-01-05 Event/Job/Inbox - Part 2-3 Complete (Outbox/Inbox + Consumers)

Part 2: Transaction + Outbox Integration - RegisterIdentityEndpoint: DbConnection → DbTransaction → Outbox write - RegisterIdentitySql: Accept NpgsqlConnection + NpgsqlTransaction (Dapper) - Fixed schema references: identity.identity → public.identity - Hash computation (SHA256) for Outbox payload integrity Part 3: Consumer + Job Implementation - IdentityCreatedConsumer: SignalR group 'identity-notifications' - MfaReminderJob: Hangfire job, 24-hour reminder, idempotent via DB tracking - IdentityAuditConsumer: Immutable append-only audit trail - Migration 0043: identity_mfa_reminder + identity_audit_log tables Testing - Unit: IdentityCreated event serialization + immutability (4 tests) - Integration: RegisterIdentityWithOutbox (3 tests: happy path, rollback, duplicate email) - Updated existing tests: Transaction management (6 test methods) Architecture - Outbox/Inbox pattern ensures exactly-once delivery - Consumers decouple from identity creation (async, independent retry) - Audit trail immutable (trigger prevents updates/deletes) - MFA reminder idempotent (tracked in DB) Status: 40% COMPLETE (event + endpoint + 3 consumers) Next: E2E tests + Hangfire job registration + Admin UI Co-Authored-By: Claude Haiku 4.5 <noreply@anthropic.com>
