More UI work

1. main STT app works in new project structure
2. UI dumps mics on startup to populate mic list
3. add missing deps (hf-xet, wave)
4. normalize audio volume when transcribing. Probably still wrong tbqh.
5. add checkbox to save audio segments & improve logic so only segments
   with speech get saved.
6. add default config settings
