feat(audit): introduce structured Audit API with export, stats, and cleanup endpoints (#4217)

# Description of Changes

- Added new REST-based `AuditDashboardController` under `/api/v1/audit`
with endpoints for:
  - Audit data retrieval with pagination (`/data`)
  - Statistics retrieval (`/stats`)
  - Export in CSV and JSON (`/export/csv`, `/export/json`)
  - Cleanup of audit events before a given date (`/cleanup/before`)
  - Retrieval of distinct audit event types (`/types`)
- Extracted web dashboard logic into `AuditDashboardWebController` (view
rendering only).
- Introduced new API models:
  - `AuditDataRequest`, `AuditDataResponse`
  - `AuditExportRequest`, `AuditDateExportRequest`
  - `AuditStatsResponse`
- Extended `PersistentAuditEventRepository` with richer query methods
(histograms, counts, top/latest events, distinct principals).
- Updated `dashboard.js` to use new API endpoints under `/api/v1/audit`.
- Enhanced authentication handlers and user endpoints with `@Audited`
annotations for login/logout/password change events.
- Cleaned up `LicenseKeyChecker` by removing unused `updateLicenseKey`
method.
- Moved admin-related controllers into `controller.api` namespace with
proper OpenAPI annotations (`@Operation`, `@Tag`).
- Improved `CleanUrlInterceptor` whitelist for new query parameters
(`days`, `date`).
