Consolidates the scattered `array_values(array_unique(array_map('intval',
$x)))` + manual positive-filter pattern behind a single lenient helper
`toIntIds(mixed $value): array` in core/Support/helpers/array.php.
- `RepositoryArrayHelper::sanitizePositiveIds()` now delegates (keeps
strict array-input contract + existing tests intact).
- Drops two private duplicates: `UserProfileViewService::normalizeIds()`
and `AddressBookService::normalizeIds()`.
- Replaces 12 inline occurrences across admin action pages with the
helper, cutting boilerplate by 3-5 lines per site.
