wireframe T-275 v3: drop inline tooltip so resting buttons are purely icon-only

The static hover-tooltip bubble beside the accept-edits icon read like a label
on the button. Remove it; the resting controls are now unambiguously icon-only,
with the label appearing only in the open dropdown, the status-bar indicator,
and the (real, on-hover) tooltip.
