Add progress display for S3 upload and transcription polling

- Add real-time progress bar with percentage for S3 upload (file size/MB)
- Replace repetitive polling output with single-line refreshing status
- Show elapsed time and poll count during transcription polling
- Add .claude/ to .gitignore
