fix: resolve array to string conversion error in EditRecord forms

- Fix DateTimeStateCast conflict when loading array data in EditRecord
- Extend Field instead of DateTimePicker to avoid datetime state casting
- Add proper array state handling for multiplePicker and rangePicker
modes
- Ensure compatibility with both CreateRecord and EditRecord forms

Fixes issue where Flatpickr components with multiplePicker() or
rangePicker() would throw "Array to string conversion" errors when
editing existing records that contain array data in the database.
