feat(admin): session edit form, payment edit/delete UI, and audit history modal

- SessionServiceCard menu gains «ویرایش» and «تاریخچه تغییرات» items.
- SessionAuditModal shows the session's change history (field, op badge,
  old->new, actor, time) from /session/{uuid}/audit-log.
- PaymentStep payment rows get edit (modal) + delete (confirm) controls for
  non-wallet payments, calling the new PATCH/DELETE payment endpoints.
- CreateStep accepts an editSession prop (prefill + PATCH); EditSessionPage
  reuses it at /patients/:recordUuid/session/:sessionUuid/edit.
