Rimuovo scaffold shadcn/ui, dipendenze e codice morto mai usati

Audit repo-wide: 44 dei 46 componenti in src/components/ui/ non erano
importati da nessuna schermata (tengo solo drawer.tsx e sonner.tsx, gli
unici referenziati). Con loro cadono 26 dipendenze diventate orfane
(radix-ui, react-hook-form, recharts, date-fns, embla-carousel, ecc.),
l'integrazione src/integrations/lovable/ (già segnalata come rimovibile
in CLAUDE.md ma mai tolta) e 11 export mai referenziati in src/lib e
src/components/crapp.

Verificato con tsc --noEmit e build: nessun riferimento rotto, bundle
runtime invariato (il codice era già escluso dal tree-shaking, quindi
qui si riduce solo il peso di installazione/manutenzione, non quello
spedito al browser).
