feat: show "appears in" albums on asset viewer bottom sheet

fix: multiple RemoteAlbumPages in navigation stack

this also allows us to not have to set the current album before navigating to RemoteAlbumPage

chore: clarification comments

handle nested album pages

fix: hide "appears in" when an asset is not in any albums

fix: way more bottom padding

for some reason we can't query the safe area here :/
