Store the full voice design prompt, not just the clipped summary

For a designed voice the instruct prompt is the voice's identity — the TTS
engine reproduces the voice from that text alone. The only copy saved was the
`note` display summary, clipped to 240 characters, which left 43 of 73 voices
cut off mid-sentence. Save the complete prompt in its own field so the engine
can register a voice from the whole description.

Existing voices keep working from the clipped copy (it still carries gender,
accent and timbre) and pick up the full text when next redesigned.

Pairs with the engine-side fix in tts-dgx-spark-faster-qwen3-tts.

+- **Designed voices now store their full design prompt.** For a designed voice the prompt IS the voice's identity — the engine reproduces it from that text alone — but the only copy saved was the `note` display summary, which is deliberately clipped to 240 characters (43 of 73 voices were cut off mid-sentence). The complete prompt is now saved in its own field, so the TTS engine can register the voice from the whole description rather than a truncated one. Existing voices keep working from the clipped copy — it still carries gender, accent and timbre — and pick up the full text the next time they are redesigned.
+
+### Note
+- This release pairs with an engine-side fix (in the `tts-dgx-spark-faster-qwen3-tts` repo) for two bugs that made custom voices unusable: stale speaker embeddings causing cloned voices to ignore the requested text entirely, and designed voices never being registered with the Voice Design engine, which silently substituted a bundled British preset. See that repo's history for details.
