Subject: [PATCH] feat(16-05): show internal-name fallback in grants matrix
 column headers (D-04)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Local Group interface gains internalName?: string | null — GET
  /module-grants/matrix already returns the field (no select on the
  groups query), only the frontend type was missing it.
- Column header text and title tooltip now use internalName ?? name
  (nullish, not truthy) — same fallback pattern as admin/groups and
  UserAccessModal. No layout change: same truncate-with-tooltip cell.
- Search filter now matches both the display name and the stored AD
  name, so neither the internal nor the original AD name search goes
  empty after the header text changed.
