feat: voice recording auto-send + recording indicator UI

Voice messages now upload and send automatically when recording stops —
no manual send button needed. The input area transforms during recording:
text field replaced by a centered pulsing red dot + "Aufnahme läuft…" label,
with a single centered red stop button below.

The old flow (record → attachment chip → manual send) treated voice like
a file attachment. New flow: tap mic → record → tap stop → auto-upload →
auto-send → stream response. Matches the expected voice message UX.
