[FEAT] Visura auto-fill, adesione volontaria, modulo NCR/CAPA

1. Fix auto-fill visura: mapping corretto suggested_sector e employees_range,
   indicatori visivi verdi sui campi auto-compilati, fatturato sempre manuale
2. Adesione volontaria: colonna voluntary_compliance, checkbox in onboarding
   step 5 quando not_applicable, toggle in settings, reset su ri-classificazione
3. Modulo NCR/CAPA: NonConformityController con 10 endpoint API,
   tabelle non_conformities + capa_actions, generazione NCR dai gap assessment,
   predisposizione integrazione SistemiG.agile (webhook + sync)
