Rewrite SelectField to use shadcn/ui Popover + Command (cmdk) pattern
for searchable selects, following best practices. This eliminates
console errors from the previous input-inside-SelectContent approach.
Changes:
- SelectField.js: Use Popover + Command for searchable fields
- Add Command component with CommandInput for proper search
- Update dialog.jsx to use Huge Icons instead of lucide-react
- Simplify searchable logic to follow PHP config directly
The Command component handles keyboard navigation and filtering
properly without focus event conflicts.
