The live partial transcript was shown as a dimmed line under the chat textarea,
but each segment only flickers there for an instant before its final lands in
the draft — the preview was unreadable noise. Remove it: realtime partials are
no longer rendered separately; finalized segments are appended straight into the
draft (where the user actually reads them). Editor dictation (inline ghost at the
caret) is unaffected.
