fix: 3 bugs — beauty icon color, appointments on dashboard, blog image edit

1. Beauty category icon: was pink (#C2185B), now uses site primary gold
   (var(--gold) / var(--gold-pale)) to match brand color

2. Dashboard now shows health requests:
   - Two new stat cards: total patients + pending requests (clickable)
   - 'آخرین درخواست‌ها' mini-table showing last 6 requests
   - Sidebar badge updates from dashboard load too
   - loadDashboard() now fetches /api/patients + /api/health-requests

3. Blog image edit fix:
   - applyCrop() now captures inputId/previewId BEFORE closeCropper()
     to prevent any potential race condition when replacing images
