Subject: [PATCH] [FIX] ARIA chat: indicatore 'sta scrivendo' + input
 multi-riga (Shift+Invio)

Risolve #418/#420 (ARIA sembrava non rispondere / serviva riaprire il pannello):
l'attesa della risposta /api/ai/ask (RAG+Claude, alcuni secondi) non mostrava
alcun indicatore -> ora compare 'ARIA sta scrivendo...' con input disabilitato
(anti doppio-invio). Indicatore rispetta prefers-reduced-motion (AGID/WCAG).

Risolve #425: il campo di scrittura era <input> a riga singola -> ora <textarea>
con Invio=invia, Shift+Invio=a capo, auto-crescita e aria-label.

common.js e' statico (no PHP/USR2): bump cache-buster ?v=20260623 su 39 pagine
(public + admin) + version.json 1.24.6.
