feat(patients): phase B3 — medical records (پرونده پزشکی)

Add patient medical-exam entries: a new PatientMedicalRecord entity
(record-scoped, CASCADE) + repository, and owner-scoped CRUD endpoints
(GET list, POST create, PATCH, DELETE) under /api/v1/patient. Wire the
"پرونده پزشکی" tab in PatientDetailPage (list + add/edit modal with title,
date and notes + delete). PHPUnit covers CRUD + ownership + validation;
Vitest covers the tab. API docs updated.
