fix(electron): streaming audio encoding not working (#12231)

fix AF-2612

<!-- This is an auto-generated comment: release notes by coderabbit.ai -->

## Summary by CodeRabbit

- **Bug Fixes**
  - Improved handling of recording status updates to prevent unwanted side effects after closing the recording popup.
  - Enhanced error handling and logging for internal communication, ensuring errors are logged and do not disrupt the user experience.
  - Refined control flow for stream encoding to avoid unnecessary errors when encoders are closed.
- **Refactor**
  - Updated popup window readiness and lifecycle management for more reliable behavior and clearer logging.
  - Adjusted recording state management to allow more precise control over status updates and emissions.
- **Style**
  - Added additional logging for popup and recording operations to aid in troubleshooting and transparency.
