fix(onnx-asr): исправлены баги интеграции после smoke-теста

- Зачем:
  - при smoke-тесте выявлены расхождения между onnx-asr API и мок-тестами.
- Что:
  - убран deprecated cpu_preprocessing из load_model.
  - sample_rate передан как keyword-аргумент в recognize().
  - исправлены имена полей SegmentResult: start_ts→start, end_ts→end.
  - добавлен device "onnx" в DEVICE_DEFAULTS и _VALID_DEVICES.
- Проверка:
  - uv run pytest -q (172 passed).
  - uv run transcribe file.mp4 --device onnx --model gigaam-v3.
