feat: payments plans, phase auto-cascade, transcripts, manual timer

- Pagamenti: totale ereditato dalla somma accepted_total delle offerte
  attive (con override) + selettore schema rate 1/2/3 step; nuova colonna
  payments.percent per rescalare gli importi preservando label/stato
- Fasi & Task: recomputePhaseStatus auto-cascade (task -> fase) su
  updateTaskStatus/addTask, fix UI stale, etichette Da iniziare/In corso/Completata
- Pagina pubblica: colori fasi (grigio/blu/#1A463C) + fasi collassabili
- Transcript del cliente visibili in tab Documenti admin e dashboard pubblica
- Timer: inserimento manuale (+30/+60, minuti liberi, data) + elimina entry
- CLAUDE.md: procedura Deploy & DB Access; push su main automatico
