Faza 3.4: Finanțe — Plăți + Cheltuieli + Cashflow

Schema:
- payments: client_id, work_order_id, user_id (operator), paid_at, amount,
  method (cash/card/transfer/mobile), reference, notes
- expenses: supplier_id, purchase_id, paid_at, category (salary/purchase/rent/
  utilities/advance/tax/fuel/tools/marketing/other), name, amount, method, ref

Logică auto:
- Payment::saved/deleted recalculează automat work_order.pay_status
  (unpaid → partial → paid) based on suma totală vs work_order.total
- WO model are noi metode: payments(), paidAmount(), balanceDue()

Filament resources (group Finanțe):
- PaymentResource: form cu legare opțională la WO + client; tabel cu
  Sum summary, filtre azi/luna_curentă/method
- ExpenseResource: 10 categorii preset, badge categ, total summary,
  filtru luna curentă
- PaymentsRelationManager pe WO: "Plăți" tab cu auto-fill client_id +
  user_id la creare

Widget FinanceOverview:
- Încasări (luna), Cheltuieli (luna), Profit (luna), Datorii clienți
- color coded: profit verde sau roșu, datorii galben/verde

Settings page fix (Filament v5):
- mount() folosește acum $this->form->fill([...]) în loc de $this->data direct
- Filament v5 cere fill explicit pentru a inițializa state-ul schemei

Seed:
- 1 plată parțială pe fișa BMW (200 din 750)
- 6 cheltuieli demo: 3 salarii, chirie, electricitate, achiziție piese

Total Filament tenant routes: 69.
