fix: persist entry selection across pages and save scroll positions

[TheBobBobs]

Summary

Allow selecting entries across multiple pages and no longer clear the selection on new queries.
When going to a previous page or query it will remember your scroll position for that page.
When searching a new query it will jump to the last entry you selected if it is in the query.

move selection logic to QtDriver from ThumbGridLayout
QtDriver will now save the full query result regardless of page_size. Allows easy bridge select across pages

BrowsingState now stores page scroll positions for it's query.
The default sort order for BrowsingState was changed to descending to match the ui.
