Auto-cancel expired consulting orders and prefill re-booking

**Features Implemented:**

1. **Auto-Cancel Expired Consulting Orders:**
   - New edge function: cancel-expired-consulting-orders
   - Changes order status from 'pending' → 'cancelled'
   - Cancels all associated consulting_sessions
   - Deletes calendar events via delete-calendar-event
   - Releases consulting_time_slots (deletes booked slots)
   - Properly cleans up all resources

2. **Smart Re-Booking with Pre-filled Data:**
   - OrderDetail.tsx stores expired order data in sessionStorage:
     - fromExpiredOrder flag
     - Original orderId
     - topicCategory
     - notes
   - ConsultingBooking.tsx retrieves and pre-fills form on mount
   - Auto-clears sessionStorage after use

3. **Improved UX for Expired Orders:**
   - Clear message: "Order ini telah dibatalkan secara otomatis"
   - Helpful hint: "Kategori dan catatan akan terisi otomatis"
   - One-click re-booking with pre-filled data
   - Member only needs to select new time slot

**How It Works:**

Flow:
1. QRIS expires → Order shows expired message
2. Member clicks "Buat Booking Baru"
3. Data stored in sessionStorage (category, notes)
4. Navigates to /consulting
5. Form auto-fills with previous data
6. Member selects new time → Books new session

**Edge Function Details:**
- Finds orders where: payment_status='pending' AND qr_expires_at < NOW()
- Cancels order status
- Cancels consulting_sessions
- Deletes consulting_time_slots
- Invokes delete-calendar-event for each session
- Returns count of processed orders

**To Deploy:**
1. Deploy cancel-expired-consulting-orders edge function
2. Set up cron job to run every 5-15 minutes:
   `curl -X POST https://your-domain/functions/v1/cancel-expired-consulting-orders`

**Benefits:**
✅ Orders properly cancelled when QR expires
✅ Time slots released for other users
✅ Calendar events cleaned up
✅ Easy re-booking without re-typing data
✅ Better UX for expired payment situations
