fix(dashboard): make ChatView mobile send fire on quick tap

The mobile send button used pointerdown + touchstart with preventDefault
and a focus-preservation dance to keep the keyboard up while sending.
That path silently failed on quick taps on iOS — only a long press
registered. Switching to plain onClick (with touch-action: manipulation
to skip the click delay) fires reliably on tap. The soft keyboard may
dismiss on send now, which is a minor regression vs. the previous
intent but vastly preferable to silent failure.

QuickChat is unchanged because it already works on mobile.

+Workaround long-standing bug where ChatView's mobile send button only
+fired on a long press — quick taps silently did nothing. The previous
+implementation used `pointerdown` + `touchstart` with `preventDefault`
+and a focus-preservation dance so the keyboard would stay up while
+sending; on iOS that path made quick taps fall through entirely. The
+button now uses plain `onClick` with `touch-action: manipulation`. The
+soft keyboard may dismiss on send, which is a minor UX regression
+compared to silent failure. QuickChat is unchanged (it already works
+on mobile).
