fix(patient): consistent debt/paid status, invoice totals, global service search

- patient_debt_rials now = session remaining (final - discount - paid), so the
  card status and invoice status stay consistent with is_paid even after a
  session is edited post-invoicing (no more '0 remaining but تکمیل پرداخت').
- InvoiceSummaryModal: remaining subtracts discount; the فاکتور status reflects
  actual settlement (تسویه شده / بدهکار), and the payments table shows a
  «مجموع پرداختی‌ها» total row.
- Add GET /api/v1/service-items (all owner services) and make the service
  picker searchable across all services without first choosing a section.
