fix(sheet): make "Mark done" mark it done

The button advanced one step round the untouched → doing → done cycle,
so pressing "Mark done" on a fresh event produced "doing it" and needed
a second press. Worse, the press after "done" cleared the status
outright rather than undoing anything.

Three states need three targets — that is the control directly above it.
This one is the commit, so it sets done and back. cycleStatus had no
other caller and is gone.
