fix(menu): close the main menu when opening a recent file

The recent-file buttons dispatched the open command without closing the app
menu, so it stayed open over the loaded drawing. Use CloseAppMenuAndRun so the
menu closes first, matching the other menu entries. Also commits the Cargo.lock
update from dropping iced's debug feature.

Fixes #103.
