Show the busy label the instant a click lands, before the first job row exists

Between pressing Transcribe and the first /jobs poll there was a blind
window where real work (POST in flight, token refresh, initial upload)
had no on-screen trace at all — the screenshot complaint 'shows
nothing'. Any non-null busy label now renders as a pipeline-style card
in the same slot the panel occupies, so feedback starts at click time.
