Refactor Windows build script for improved readability and consistency

- Cleaned up whitespace and formatting in build_windows.py for better readability.
- Consolidated environment variable setup for stdout and stderr.
- Streamlined subprocess command calls by removing unnecessary line breaks.
- Enhanced error handling and logging for better debugging.
- Updated comments for clarity and consistency.

Update updater.py to improve checksum verification logic

- Modified checksum verification to prioritize specific .sha256 files matching installer names.
- Added fallback logic to check for any .sha256 file if no specific match is found.

Enhance update manager UI with download progress dialog

- Introduced DownloadingDialog to provide feedback during update downloads.
- Updated MainWindow to manage the new downloading dialog and handle its lifecycle.
- Removed the skip version functionality from the update dialog as per new requirements.

Refactor update manager UI tests for clarity and maintainability

- Removed tests related to the skip version functionality.
- Updated test cases to reflect changes in the update manager UI.
- Ensured all tests are aligned with the new dialog structure and signal emissions.
