fix(gui): stop renaming a folder from swallowing the click that commits it

The folder's name box commits on blur, and blur fires on the PRESS —
before the click that press belongs to. Committing re-rendered, and the
re-render replaced every tile in the open folder, so by the time the
click was dispatched the tile under the pointer was detached and the
delegated handler never saw it. Typing a name and then tapping an app
in the folder — the path a brand-new folder puts the user on — renamed
the folder and did nothing else; the app only opened on a second click.

Rebuild the folder's contents only when they actually differ from what
is on screen. A rename doesn't change them, so nothing is detached, and
a background refresh no longer throws away hover/focus either. Tiles
that survive get their drag resting-rects cleared, since the card can
have moved under them since the rects were taken.
