feat: Audit Inspector Minimal API endpoints (MapAuditInspector, read-only)

[samtrion]

User Story

As a compliance officer or developer, I want read-only minimal API endpoints for querying the audit trail, so that I can review command history by user, time range, or outcome without direct database access.

---

Requirements

• Create AuditInspectorOptions: BasePath = "/pulse/audit", RouteGroupName = "Pulse Audit Inspector".
• Create AuditInspectorEndpoints (static class, read-only — no replay or dismiss):
  • GET {base}/stats → IAuditManagement.GetStatisticsAsync()
  • GET {base}/entries?commandType=&userId=&from=&to=&result=&take=50&skip=0 → QueryAsync(filter)
  • GET {base}/entries/{id} → single record or 404
• Add MapAuditInspector(this IEndpointRouteBuilder, Action? configure = null) returning IEndpointConventionBuilder.
• No built-in authorization.

---

Acceptance Criteria

• All three read-only endpoints respond correctly.
• All filter query-string parameters bound correctly.
• 404 when record not found.
• Unit tests cover all three endpoints.

Dependencies

• Requires feat: Define Audit Trail schema, interfaces, and options
