Introduce la primitiva Card e sistema tocco e accessibilità dei componenti

`rounded-3xl bg-card p-4 shadow-card` era ricopiato a mano 22 volte: cambiare
raggio od ombra voleva dire toccare venti file. `Card` in `ui-bits.tsx` è ora
l'unica definizione delle superfici, con la gerarchia dei raggi scritta invece
che implicita (contenitore 3xl, elemento interno 2xl, controllo full).

Tocco e tastiera:
- i chip presenza di `EventoCard` erano alti ~28 px ed è il controllo più
  toccato dell'app: ora `min-h-11`, con 8 px di spazio fra l'uno e l'altro;
- stessa cura per il link «Apri partita», la chiusura di `CelebrazioneBadge` e
  il titolo di `SezioneTendina`;
- `aria-pressed` sui controlli a stato, `aria-controls` sulle tendine (che
  avevano `aria-expanded` senza il pannello a cui si riferisce), `aria-busy`
  sui caricamenti;
- `BottomNav`: lo stato attivo era comunicato solo dal colore. Ora cambia
  anche il peso del testo, compare una barretta sopra l'icona e c'è
  `aria-current="page"`. La voce «Home» diventa «Oggi», che dice cosa
  contiene. La barra è un materiale traslucido con bordo sfumato al posto
  della riga netta.
- `Barra` espone `role="progressbar"` con i valori.

Il testo sotto i 12 px è sparito (108 occorrenze fra `text-[9px]`,
`text-[10px]` e `text-[11px]`): sotto quella soglia la leggibilità cala e su
iOS non scala con Dynamic Type. La gerarchia la fanno peso e maiuscolo.

`Avatar` aveva `alt="Foto di 12"` quando il fallback è il numero di maglia —
non descrive niente e il nome è già scritto accanto, quindi alt vuoto. Aggiunti
`width`/`height` per non far saltare il layout al caricamento.
