fix: Select defaults + confirm responsive pattern + convert to AlertDialog

1. Fixed Select Field Default Value ✅
   Problem: Select shows empty even with default/saved value
   Solution: Ensure select always has value

   const selectValue = (value || field.value || field.default) as string;
   <Select value={selectValue}>

   Priority: current > saved > default
   Result: ✅ Select always shows correct value

2. Confirmed Responsive Pattern ✅
   ResponsiveDialog already working correctly:
   - Desktop (≥768px): Dialog component
   - Mobile (<768px): Drawer component
   - useMediaQuery hook detects screen size

   ✅ No changes needed - already correct!

3. Converted to AlertDialog ✅

   A. Orders/Detail.tsx - Retry Payment
      - Was: Dialog (can dismiss by clicking outside)
      - Now: AlertDialog (must choose action)
      - Better for critical payment retry action

   B. Orders/index.tsx - Delete Orders
      - Was: Dialog (can dismiss by clicking outside)
      - Now: AlertDialog (must choose action)
      - Better for destructive delete action

   Benefits:
   - ❌ No close button (forces decision)
   - ❌ Can't dismiss by clicking outside
   - ✅ User must explicitly choose Cancel or Confirm
   - ✅ Better UX for critical/destructive actions

Component Usage Summary:
- Dialog: Forms, settings, content display
- Drawer: Mobile bottom sheet (auto via ResponsiveDialog)
- AlertDialog: Confirmations, destructive actions

Files Modified:
- GenericGatewayForm.tsx: Select default value fix
- Orders/Detail.tsx: Dialog → AlertDialog
- Orders/index.tsx: Dialog → AlertDialog
