fix(dashboard): keep keyboard up on send tap; hide status bar with keyboard

Two mobile chat regressions addressed together:

1) ChatView send button: preventDefault now fires on pointerdown for
   touch pointers, before iOS blurs the textarea. The previous
   onMouseDown.preventDefault was too late on iOS (mousedown is
   synthesized after touchend, by which point the keyboard has
   already started dismissing). Click still runs the action so quick
   taps remain reliable.

2) ExecutorStatusBar: hidden on mobile while keyboard is open,
   mirroring MobileNavBar. The bar is position:fixed against the
   layout viewport, which iOS leaves anchored below the keyboard;
   during a swipe/pan it would slide over the messages list.
