fix(mobile): removeClippedSubviews=false on grids — stop thumbnails vanishing on scroll

Android FlatList defaults removeClippedSubviews=true, which detaches off-viewport
subviews; expo-image frequently fails to re-render them when they scroll back in →
blank thumbnails (bug-report f181d382 2026-06-07, recurring). Disable on all heavy
image grids: scene grids (Scenes/Site/Studio/Tag/Performer) + movie poster grids.
