Footer: rimuove il form contatti e riorganizza in 3 colonne

- Rimossa la colonna "invia messaggio" (nome, cognome, telefono, mail,
  messaggio) e l'import ContactForm inutilizzato.
- Griglia a 3 colonne con contenuto centrato, logo incluso.
- Training e Servizi allineati alla riga "Promuoviamo il movimento...".
- Altezza del footer ridotta (padding compattato).
