KatMultiImagePickerScreen class
A grid-based picker for selecting multiple photos, backed by
package:photo_manager's AssetEntity.
The app bar's add-photo action pushes galleryRouteName - the host app
is expected to register that named route to let the user browse their
photo library and return the chosen assets via
Navigator.pop(context, List<KatAssetEntity>). The check action pops this
screen with the currently picked assets.
Long-press an asset to enter selection mode, then tap assets to toggle their selection (highlighted in green). Scrolling to the bottom of an overflowing grid calls onLoadMore; pulling down calls onRefresh - both optional, for a host app that paginates or refreshes its own data.
