fix(files): an upload is announced once, as an upload, and a finish shows in Files at once

An upload that came back done was announced twice: by the upload dialog ("File uploaded") and
again by the tray, which saw a job turn done ("Downloaded: …"). The dialog now marks its job as
announced, so the queue keeps it for the tray but does not say it again. An upload the worker
converted first is still the tray's to announce, now as "Uploaded: …".

A finished job's notice offered "Open" while Files still listed the folder without it (its own
poll runs every 15 s): the tray now refreshes the library the moment it sees a finish.
