fix(mobile): image pager direction + end-arrows; reset --kb on composer blur

Browse Source 
- Pager: force the staged (opposite-edge) frame to PAINT (void offsetWidth) before animating in, so the
  incoming image enters from the correct side (was appearing from the exit side). Hide prev-arrow at the
  first image and next-arrow at the last.
- #1: keyboard closed after reply-cancel but the --kb lift stayed (empty gap). Add keyboardDidHide reset +
  a composer-blur fallback that drops --kb when focus leaves the composer.
Build marker -> 2026-07-18-batch119.
