fix(web): kebab anti-clipping partajat + panou admin redenumit + tabel mapari compact

- "Panou admin" -> "Conturi clienti" (titlu, antet, link meniu hamburger)
- Kebab actiuni mutat in component partajat (base.html) cu position:fixed
  pozitionat din JS: .tablewrap{overflow-x:auto} inducea overflow-y:auto care
  taia dropdown-ul pe ultimul rand (meniul admin nu se vedea). Sters CSS local.
- Mapari salvate: Salveaza/Sterge mutate in kebab (legate prin form=); coloana
  "In coada" doar checkbox (macro autosend_toggle compact, semantica de prezenta
  pastrata); select cod RAR limitat la 240px -> tabelul incape fara scroll.
