fix(client): catalogo mobile, BC/navigator/profilo/amici

- Catalogo Hippiehotel responsive su mobile (finestra 96vw/72vh, rail
  tappabile, sotto-pannelli ristretti); duckie ripristinato come entita
  separata (revert modifiche scrollbar sul suo CSS)
- BC e catalogo normale seguono entrambi il toggle tema; il duckie non
  duplica piu il logo nelle pagine info_duckets
- Navigator: highlight della tab segue currentTabCode (era bloccato su
  Pubblici mentre il contenuto cambiava)
- Inventario: link inventory/show/<tab> per deep-link a una scheda
- User Profile: avatar visibile e allineato a bg/stand, finestra piu
  grande, bordi puliti, Created/Last login mostrano il valore, bottoni
  Change Looks/Rooms/Change Badges/Add friends/Achievement funzionanti
- Amici: header non piu sovradimensionati e teste avatar inquadrate
  (regole flat: quelle annidate .nitro-friends{&...} non si applicavano)
