Move search indicator from absolute-positioned overlay into sort toolbar
(or dedicated search-bar-row for artists/genres views). Shows indicator
on empty-state screens. Fix cover art not displaying for expanded album
tracks by checking expandedAlbumId before the albumName guard. Add
ScanWarning model bindings.
repeat() as child content of lit-virtualizer bypasses virtualization,
rendering ALL items instead of only visible ones. This caused 2+ minute
loading times and UI freezing with large libraries.
The correct approach: use lit-virtualizer's native .renderItem and
.keyFunction properties which integrate with its scroll-based viewport
management.
- cover-grid: all 3 virtualizers (single, before-split, after-split) use repeat() with album.ID key
- artists-view uses repeat() with artist.ID key
- genres-view uses repeat() with genre.name key
- Removed gridKeyFunction (now inlined in repeat calls)
- Removed .renderItem and .keyFunction properties from all virtualizers
