Subject: [PATCH] Replace Column+verticalScroll with LazyColumn for request
 cards

With Column, all N request cards are composed simultaneously regardless
of visibility. With LazyColumn, only visible cards (~5-10) are in the
composition tree, so select/deselect all only recomposes visible items
instead of every item in the list.
