KatMultiUploadFile<T extends KatMediaAsset> class
A bordered panel for picking files/photos/videos to upload, previewing what's already been picked, and removing any of them.
onPickFile is always shown; onPickImage and onPickVideo only when
provided, so a host app can leave out camera-based actions it doesn't
support. type also controls how medias is previewed below the
actions: a photo grid for FileType.image, a plain file list otherwise.
T is whatever model the host app already uses for a picked/uploaded item - see KatMediaAsset for the properties this widget reads off it.
