feat(5.9): US-007 - responsive pagini de continut (card Mapari, scroll contained Jurnal/Nomenclator/Admin, formulare stivate)

- base.html @media(max-width:767px): clasa .tabel-card (card per rand) scopata
  SEPARAT de .tabel-trimiteri 5.8; reguli formular full-width + butoane >=44px
  scopate pe #card-cont / #form-test-cheie / #filtre-jurnal (marker US-007)
- _mapari.html: tabel-card + data-eticheta pe toate 4 tabelele; override select
  in card local (evita batalia de specificitate cu stilul inline)
- _integrare.html: id=form-test-cheie (ancora de scope pe formularul de test)
- R12 per-tabel: Mapari=card; Jurnal/Nomenclator/Admin=.tablewrap scroll contained;
  Cont/Integrare=fara tabele (doar formulare)
- tests: +3 (tabele clasa responsive, formulare full-width, regresie carduri 5.8)
- suita: 838 passed, 1 deselected
- prd.json US-007 passes=true + notes; progress.txt
