ui: improve ACME edit/apply button visibilty

multiple users were confused[0], as they did not interpret the 'icon only'
in the toolbar as a button (and it did not help that we prevented
the cursor to change)

to improve it, make the button a normal one again, and add some
text for context (this is more inline what we do elsewhere in toolbars)
