Simplified UI (#136)

* refactor: Update translation option in transcription filter

- Update the translation option in the transcription filter to use a more concise label
- Remove unnecessary code related to file output in the transcription filter
- Improve the handling of whisper model paths in the transcription filter
- Set the default language to "auto" in the transcription filter properties

* refactor: Improve error handling in model-downloader.cpp and transcription-filter-callbacks.cpp

* refactor: Improve error handling in model-downloader.cpp and transcription-filter-callbacks.cpp
