feat(widgets): iOS widget improvements (#19893)

* improvements to error handling, ability to select "Favorites" as a virtual album, fix widgets not showing image when tinting homescreen

* dont include isFavorite all the time

* remove check for if the album exists

this will never run because we default to Album.NONE and its impossible to distinguish between no album selected and album DNE (we dont know what the store ID is, only what iOS gives)
