Covers AuditLogQueryService filtering/paging/actor-name join,
AuditLogResponse mapping, AuditLogsController, AuditService.LogAsync
and actor-claim resolution, WebhookResponse/WebhookDeliveryLogResponse
mapping, CreateWebhookRequestValidator, WebhookQueue, and additional
WebhookDispatcher branch coverage (scope routing, disabled webhooks,
delivery exceptions).
Excludes WebhookBackgroundService and WebhookRetryBackgroundService
from coverage: both resolve a DI-scoped concrete MicCheckDbContext via
IServiceScopeFactory, which requires a live DI container/DB per
CLAUDE.md's no-InMemory/WebApplicationFactory rule. Their query and
dispatch logic is covered by WebhookRetryTests/WebhookDispatcherTests.
## Summary
- Extract `IMicCheckDbContext` and mock DB access with Moq instead of the EF InMemory provider, per CLAUDE.md testing guidelines.
- Rewrite HTTP-pipeline tests to exercise controllers/auth handlers directly instead of `WebApplicationFactory`.
- Remove tuple return types across the API in favor of named records (`PagedResult<T>`, `ProfileUpdateResult`, `ApiKeyCreationResult`).
## Test plan
- [x] `dotnet build` (full solution)
- [x] `dotnet test tests/api/MicCheck.Api.Tests.Unit` — 187/187 pass
- [x] `dotnet test tests/api/MicCheck.Api.Tests.Integration` — 8/8 pass (live API + Postgres via Aspire)
- [x] Verified Aspire AppHost/dashboard starts and API responds
