T17 review fixes: hidden numbers draw, empty edits and read-only commands change nothing, hints stay in a ghost-cut row, the newest cursor leads, a composition undoes in one step, call keys carry their place, references count matches, trailing-space hits and **/ globs, name-only switcher marks, pin and remove stay on their button, settings show their places; decimals moves to typography::format
