style(workflow): pin the canvas title to the 30px chrome midline

With a chat docked the toggle/switcher pills hide and the chrome cluster
collapsed to the title's own line-height, floating it ~5px above the chat
title across the divider. The cluster now holds a fixed 30px height, so the
workflow title centers on the same y=22 midline in both states and nothing
shifts when the chat closes.
