fix(gui): keep a folder name typed right up to the moment it closes

The name box commits on blur, and every exit that goes through a pointer blurs
it while the folder is still open — so clicking outside, or launching an app
from inside, keeps what was typed. Escape does not: _closeGroup clears
_openGroupId first and only then moves focus to the tile below (or removes the
card outright), so the blur arrives with no open folder to rename and
_renameGroup drops it. A brand-new folder opens with its name selected for
exactly this edit, so "type Games, press Escape" — the obvious way to dismiss
a dialog — was the path most likely to lose it.

Commit the pending name on the way out, before the folder id is gone.
