fix(web): keep focus in place after removing a media API key (#148)

Remove unmounts itself once clicked, so focus fell to the body and the
settings dialog pulled it back to its popup a frame later. Whatever field
the user (or a test) focused in that frame lost focus again; in CI the
cleared transcription URL was still sent on the next save. Remove now
moves focus to the key field before it disappears.
