About: testi aggiornati e rimozione sezioni Metodo, Vision, StoryLab

- Testi riscritti da documento cliente: about.about.body, convenzioni.item1/item2
  (rimosso "gratuita"), studios.body1 (versione breve). Seed + migrazione DB
  idempotente (guardia via frammento LIKE, rispetta le modifiche da pannello).
- Rimosse dalla pagina le sezioni marcate "LEVARE" nel documento: Timeline/StoryLab,
  Metodo (presente in home) e Vision. I tag restano nel seed per un eventuale ripristino.
