Restore ListScrollbar, TrackRow and AlbumPageView to their pre-scrollbar state (always-visible scrollbars). The per-row hover-reveal only revealed the bar over track rows, not over the whole scrollable viewport, so on mixed-content views (Artist, Label) it felt incomplete. Card sizing (Album/Playlist/Radio at 200px) is kept. cc

// Custom vertical scrollbar for a ListView — Slint's built-in one is
|
|
// too thin and its thumb has no minimum size, so on a thousands-row
|
|
// list it shrinks to a sliver. This sits in its own gutter (not over
|
|
// the rows), is thicker, keeps a minimum thumb height, and is
|
|
// draggable. Bind `viewport-y` two-way to the ListView and feed it the
|
|
// list's viewport/visible heights.
