-Fix mobile chat send button silently failing on quick taps. Both the
-ChatView and QuickChat send/stop buttons had `onPointerDown` and
-`onTouchStart` handlers that each invoked the send/stop action — on a
-quick mobile tap both handlers fire, so the action ran twice in rapid
-succession. The second invocation closed the first one's SSE stream,
-which the server treated as a cancel, leaving the chat with no output.
-A long press happened to suppress one of the events, so holding the
-button "worked" while quick tapping silently failed.
-
-The handlers now share the existing `handledMobile*Ref` flag so only
-the first event for a given tap actually fires the action. The send
-button also gets `touch-action: manipulation` and an expanded invisible
-hit area so slightly-off taps don't fall through to the surrounding
-textarea (which would dismiss the keyboard without sending).
