feat(clinic-services): two-page section→services flow matching Figma

Restructure clinic-services from two-pane to Figma two-view flow:
sections card grid (name, edit, activate/deactivate, 'بخش جدید' modal) →
click a section → its services card grid with breadcrumb back. Service
card matches Figma: overflow menu, active badge, base price, average
time badge, staff chip. Add duration_minutes to ServiceItem (migration
+ create/update + form field). Update clinic-services.md.

(Version20260713050014 syncs pre-existing entity/schema drift.)
