Hide facility/location when it's the «نامشخص» placeholder — omit, don't print it

When a listing's facility is the unknown placeholder, don't show «مرکز درمانی
(نامشخص)» anywhere — just leave the location out. Gated on HasRealEmployer:
- cards (shift/job/recommendation): the 🏥 facility line is omitted
- shift detail: H1 drops the «— نامشخص» suffix; title/description use city only;
  «شیفت‌های دیگر این مرکز» hidden; report label generic
- job detail: subtitle drops 🏥, keeps 📍 city; title/description city-only
