Subject: [PATCH] fix(history): fall back to raw transcript when polished text
 is empty + copy button on raw panel

When polishing returns an empty finalText (errorCode stays null), the History
"Copy" button copied an empty string, so the raw transcript that is still
visible in the UI could not be recovered. Re-transcribe does not apply here
(ASR succeeded; polish is what failed).

- onCopy: fall back to rawTranscript when finalText is blank
- raw panel: add a dedicated copy button (shown only when rawTranscript exists)
- reuse existing common.copy / common.copied, no new i18n; frontend-only

Complements #653 (polish identical to raw); independent of the in-progress
history re-polish work (#666/#694). No backend/IPC changes.
