Refactor Windows installer configuration and improve logging functionality

- Changed installation scope from "perMachine" to "perUser" in the Windows installer configuration.
- Updated installation directory from "ProgramFiles64Folder" to "LocalAppDataFolder" for user-specific installations.
- Enhanced the configuration saving method to create parent directories if they don't exist.
- Improved the main window script loading logic to support multiple installation scenarios (development, PyInstaller, MSI).
- Added detailed logging for script loading failures and success messages.
- Implemented a new method to reconfigure logging settings at runtime, allowing dynamic updates from the settings dialog.
- Enhanced the settings dialog to handle configuration saving, including log level changes and error handling.
