feat: اصلاح سند payment corrections + audit-log & daily P&L views

Backend:
- POST /orders/{id}/payments/corrections (Manager/Owner): void wrong
  payments (marked Refunded, never deleted) and/or record replacements
  atomically; mandatory reason; requires an open register shift; full
  before/after written to the immutable audit trail.
- GET /orders/closed?date= — closed orders of one Iran-calendar day,
  paged, the browsing surface for corrections.
- CalculateExpectedCash now subtracts cash refunds so corrections keep
  the drawer expectation honest.

Dashboard (reports screen now has three tabs):
- عملکرد و سود: existing KPIs/charts + new day-by-day breakdown table
  (orders, revenue, expenses, net profit per Jalali day).
- اصلاح سند: closed-orders browser with payment chips + correction
  dialog (void checkboxes, replacement rows, live balance, reason).
- گزارش عملیات: filterable audit-log viewer (category, Jalali range,
  branch) with expandable structured details.

fa/en/ar translations included. 86 backend tests pass; dashboard tsc clean.
