MangaScreen: Ditch the expanded app bar (#7470)
Animating the content padding that's used for the lazy list is heavy. A simple fix to *just* offset the list is blocked by a Compose fling issue (b/179417109). So I decided to go with the previous layout of this screen by putting everything in the list. MangaInfoHeader is split into separate composables to avoid jank when the item is being inflated.
