feat(parcel-sync): add LIMITE_UAT to sync package everywhere

All sync paths now include both admin layers (LIMITE_INTRAV_DYNAMIC +
LIMITE_UAT) as best-effort alongside terenuri + cladiri:
- export-bundle (hero buttons)
- sync-background (fire-and-forget)
- auto-refresh scheduler (weekday nights)
- weekend deep sync (weekend nights)
- freshness check (export tab badge)

LIMITE_UAT rarely changes so incremental sync will skip it almost
every time, but it stays fresh in the DB freshness check.
