feat: replace patient messages tab with pinnable notes

Port the tauri AddNoteModal notes feature into the admin patient case-file,
replacing the mislabeled «پیام‌ها» (SMS log) tab with «یادداشت‌ها».

Backend (src/Patient):
- PatientNote entity + repository (record-scoped, pinned-first ordering)
- CRUD endpoints on PatientController: GET /notes, POST /note,
  PATCH /note/{uuid} (edit body + toggle pin), DELETE /note/{uuid}
- author display name captured server-side from the current user
- migration for patient_notes; docs/api/patient.md updated

Frontend (assets/admin):
- NotesTab: compose box, newest/oldest sort, pinned-first list with
  accent rail + pin/edit/delete, edit modal, confirm-delete, empty state
- tab key/label/icon messages -> notes; onAddNote deep-links the notes tab

Tests: PatientNoteTest (create/list-order/edit/pin/delete/validation/ownership),
PatientDetailPage notes cases (render/empty/pin/create).
