fix: mobile diff comment input placeholder and review comments pill

Use a shorter comment placeholder on mobile (drop the Cmd+Enter hint that has
no touch equivalent) so it no longer clips in the auto-sized textarea.

Add a remove (x) button to the review comments pill, matching the annotation
and dev-server-log pills, and stop the mobile touch-target min-height/width
from inflating the pill close buttons.
