Port the tauri /files/create-service page (payment mode) to the admin SPA
and back it with real multi-part session settlement:
Backend:
- New SessionPayment entity (session_payments table): partial payments
per session with method (wallet/pos/cash/card), amount, paid_at, actor
- PatientSession: settlement discount (percent/fixed), discount_rials,
paid_at, payments relation; remaining debt derived from
final - discount - paid total
- POST /api/v1/session/{uuid}/payments: register a partial payment;
wallet method debits the patient wallet; zero remaining marks paid
- PATCH /api/v1/session/{uuid}: accepts discount_type/discount_value
(null removes) and paid_at, backward compatible
- New error codes: ERR_SESSION_PAYMENT_INVALID/_EXCEEDS,
ERR_SESSION_DISCOUNT_INVALID
- Migration + 14 functional tests (partial/full/wallet/exceed/discount)
Frontend (admin):
- SessionPaymentPage: two-step stepper (پرداخت ← جزییات) ported from
tauri AddService payment mode — service cost, settlement discount
input, Jalali payment date, wallet balance, 4-method payment accordion,
paid-list box, details summary
- SessionStepper + stepper/payment icons ported verbatim from tauri SVGs
- «تکمیل پرداخت» on SessionServiceCard now navigates to the payment page
(replaces the small settle modal on PatientDetailPage)
- Routes for patients/ and my-patients/ variants; vitest coverage
- docs/api/patient.md updated
