feat(audit): CSV/Excel export for system-audit via core primitive

Third consumer of the generic export primitive. Adds a
GET /admin/system-audit/export endpoint, the reusable export dropdown
to the list titlebar, and wires initListExport() into the page JS.

- pages/audit/system-audit/export().php: guard + ABILITY_SYSTEM_AUDIT_VIEW,
  reuses the existing filter-schema.php via gridParseFiltersFromSchemaFile
  so exported rows match the grid under the same filters, caps the limit
  at 5000, and declares 11 ExportColumns (ID, created, event, status,
  channel, actor, actor email, target type/uuid, request id, error code)
  with translated enum labels for outcome/channel.
- module.php: new admin/system-audit/export route.
- index(default).phtml: app-list-export-dropdown partial placed above the
  existing purge action; exportUrl added to pageConfig via
  lurl('admin/system-audit/export').
- admin-system-audit-index.js: imports initListExport and invokes it
  whenever config.exportUrl is present.
- i18n de/en: new "Actor email" key (required by TranslationKeysTest).

Gates: PHPUnit 1880 OK, PHPStan 0 errors, module:sync ok.
