refactor: replace AssetDropdownItem with FormDropdownItem

- Create minimal FormDropdownItem interface in dropdown/types.ts

- Remove dropdownItems computed from useAssetWidgetData

- Transform assets in WidgetSelectDropdown using getAssetFilename()

- Delete assetDropdownTypes.ts and assetDropdownUtils.ts

- Update all FormDropdown components to use FormDropdownItem
