Enhance Docker image pulling process and remove Bitcoin Core UI

- Improved the Docker image pulling process in the startup script with a spinner for better user feedback.
- Added a tip for monitoring progress in Docker Desktop.
- Removed the Bitcoin Core HTML UI file as it is no longer needed; replaced with connection info alert in the app view.
- Updated the app view to provide direct connection details for Bitcoin Core instead of opening a separate page.
