Bottom safe-area taps hit timeline

Medium Severity

Bottom spacing moved onto the pointer-events-none composer overlay, but the removed chat-composer-lower-chrome sibling was the only in-flow layer in that band with default pointer hit-testing. Taps in the safe-area and extra bottom padding can reach the scrolling timeline underneath instead of being absorbed above it.
