Show deleted entity name beside target id in admin Audit Log

Task #133: Admin Audit Log rows now display the deleted item's
human-readable name next to its `<type> #<id>` target reference
without admins having to expand the JSON metadata.

Changes
- artifacts/tx-os/src/pages/admin.tsx
  - New helper `forceDeletedEntityName(entry, lang)` that pulls a
    localized display name from a force-delete row's metadata.
    Priority: nameEn/nameAr/displayNameEn/displayNameAr (lang-aware)
    > plain `name` > `@username`.
  - `AuditLogRow` renders an additional muted "Target: <type> #<id>
    · <name>" line beneath the summary for force-delete entries that
    expose a name. When no summary is generated, the existing target
    fallback line is upgraded to include the name as well.
- artifacts/tx-os/src/locales/en.json, ar.json
  - New `admin.audit.targetWithName` key with English and Arabic
    translations.

Behavior
- Names respect the active language (Arabic preferred when lang=ar,
  with graceful fallback to the other locale, then `name`, then
  `@username`).
- Non-deletion rows and deletion rows whose metadata lacks a name
  are unchanged — no extra line is rendered, so there is no
  regression for existing entries.

Verification
- `pnpm exec tsc --noEmit` in artifacts/tx-os passes after running
  `pnpm --filter @workspace/api-spec run codegen`.
- E2E test (Playwright) confirms the new line renders for both a
  service.force_delete row (English-only metadata) and an
  app.delete force row (English + Arabic metadata), and that the
  Arabic UI surfaces the Arabic name when present and falls back to
  the English name when not.

Follow-ups proposed
- #194 Persist user display names in user.delete audit metadata.
- #195 Log every service deletion, not only forced ones.
