refactor(apps): optimize home app list loading and grid layout

1. refactor home app list loading logic: use seen set instead of map, handle deduplication with spark priority
2. add vertical scrolling for small app grid when not using virtual scroll
3. remove unnecessary overflow-y-auto from main container
