Task #243: Admin audit log — focused readability + actor-filter subset

Landed a tight subset of the 13-item umbrella, mirroring the proven
narrow-then-defer pattern from #242:

- #195 — Plain DELETE /api/services/:id now writes a `service.delete`
  audit row carrying nameEn + nameAr (force-with-deps still uses the
  dedicated `service.force_delete`). Added matching `service.delete`
  formatter case + EN/AR i18n keys, and surfaced nameAr on the existing
  `service.force_delete` summary.
- #197 — `actorUserId` filter for `/admin/audit-logs` and CSV export.
  openapi.yaml updated, codegen regenerated, server filter wired through
  parseFilters/buildWhere with 400-on-invalid handling, AuditLogPanel UI
  got an actor dropdown wired into params + export URL + reset, and a
  new audit-logs-actor-filter API test (4 cases) covers list narrowing,
  exclusion, invalid input, and CSV export.
- #178 — Formatter unit tests for user.delete (id-only, EN/AR display
  name resolution, force flag, force + name) and the new service.delete
  (id-only, EN/AR), 11 new cases (33/33 pass).

Skipped #194 — already implemented; users.ts DELETE persists displayName
fields and audit-summary already renders user.deleteWithName/forceDeleteWithName.

Deferred via follow-ups (no duplicate of existing #182/#183/#184):
- F1: #196 recent-activity endpoint + 5 admin panels
- F2: #205+#206+#208 permission history CSV/name resolution/timeline
- F3: #209+#210 cascade/bulk audit rows + e2e UI spec for History tabs

Validation: tx-os typecheck clean; pre-existing executive-meetings.ts
errors not regressed; all targeted server tests pass (delete-force-warnings 10,
audit-logs target-filter 7, forced-only 6, audit-log-coverage 27, new
actor-filter 4, broader audit/services sweep 40); e2e test verified actor
dropdown rendering, filter behavior, readable Arabic service.delete summary,
and CSV export honoring the filter.
