feat(01-04): PaymentStatus — totale accettato + righe stato pagamento (senza importi)

- Mostra accepted_total formattato in EUR (unico importo permesso — LOCKED)
- Righe pagamento: solo label + badge stato (da_saldare/inviata/saldato)
- Nessun importo singolo visibile al cliente (T-04-001 mitigato)
- Dot colorato + badge per ogni riga: blu=da_saldare, giallo=inviata, verde=saldato
