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.
