Rimuove le dipendenze da Lovable: l'app non gira più nel suo editor

Tolti il login social e il reporting errori verso l'editor Lovable (codice
morto, mai importato o no-op in produzione), la cartella .lovable/ con i
piani dell'editor, e riscritto vite.config.ts senza il preset
@lovable.dev/vite-tanstack-config, esplicitando gli stessi plugin
(TanStack Start, Tailwind, tsconfig-paths, React, Nitro/cloudflare) che
forniva.
