feat: port tauri create-service page as 3-step new-session wizard

Backend:
- Add session_at and inventory_package_id to patient_sessions, new
  session_consumables table (migration Version20260716102537)
- New SessionConsumable entity/repository mirroring SessionService;
  price snapshot, quantity >= 1, tenant-scoped silent skip
- PatientService::createSession accepts session_at, consumables[] and
  inventory_package_uuid; consumables are fully patient-paid (no
  insurance coverage) and added to final_price_rials
- Functional tests: success, foreign-tenant/unknown skip, empty and
  zero-quantity edges (tests/Patient/SessionConsumableTest.php)
- docs/api/patient.md updated for the new Create Session fields

Frontend (admin):
- NewSessionPage rewritten as the tauri /files/create-service 3-step
  wizard (ایجاد سرویس ← پرداخت ← جزییات) using SessionStepper
- New CreateStep: acceptance date/time (Jalali), section/service/staff,
  consumables with counters, package select, conditional insurance
  block (insured service or insured patient profile), price summary
- PaymentStep/DetailsStep extracted from SessionPaymentPage and shared
  between both pages (behavior unchanged, tests still green)
- UserTick and FilesServiceAddCard icons ported verbatim from tauri
- Vitest coverage for the wizard incl. empty-data states
