Rimuove 43 componenti shadcn inutilizzati e installa motion

Dei 45 componenti in `src/components/ui/` solo `drawer` e `sonner` erano
importati da qualche parte. Gli altri 43 — e con loro ~45 dipendenze: tutti i
`@radix-ui/*`, recharts, react-hook-form, date-fns, embla, cmdk, input-otp,
react-day-picker, react-resizable-panels, class-variance-authority,
tw-animate-css — erano superficie di aggiornamento e di sicurezza pagata a
vuoto. Stessa sorte per `src/hooks/use-mobile.tsx`, mai importato. `zod`
resta: lo usano tre route API.

Le dipendenze dirette passano da 50 a 21. Il bundle client NON cala per
questo: quel codice non era importato e il tree-shaking già lo escludeva.

Nella direzione opposta entra `motion`, l'unica aggiunta: serve per le molle
interrompibili che nessuna `@keyframes` CSS può dare (vedi DD-021). Costa ~42
KB gzip, che le rimozioni non compensano — il bundle client passa da 267 a
308 KB gzip.
