Maintain portable installation integrity and document exceptions

[Gabriel Dufresne (GabrielDuf)]

This pull request significantly improves portable mode support in UniGetUI, especially for the Windows .zip release. It ensures portable mode is enabled by default for the .zip, relocates temporary and cache files to the portable directory, and introduces a user-friendly way to import settings from a previous installation. It also updates documentation to reflect these changes and upgrades the Pinget dependency.

Portable mode improvements:

• The Windows .zip release now ships with the ForceUniGetUIPortable marker, making it portable out of the box. Documentation is updated to clarify that only the installer and non-Windows archives require manual activation of portable mode.
• All temporary files, logs, and the WebView2 profile are now stored in the portable folder (AppPaths.ScratchDirectory) rather than system temp directories, ensuring no data is left behind on the host system.

Settings import feature:

• On first run in portable mode, if previous settings are detected, a notification banner offers to import them. The user can import settings with a single click, and the UI provides feedback on success or failure.

Installer and update enhancements:

• The auto-updater now uses a new helper (AutoUpdaterInstallerArguments) to ensure that updates to portable copies are performed in place and do not accidentally convert them to regular installs.

Third-party integration:

• Pinget's data storage is redirected to the portable folder in portable mode, preventing it from writing to the user's profile.
  Dependency updates:

• Upgrades Devolutions.Pinget.Cli.Rust to version 0.11.0.

These changes provide a more robust and privacy-conscious portable mode, improve the user experience for portable users, and ensure better consistency across platforms.

• The new success title and message keys are also missing from src/Languages/lang_en.json, so translation-source synchronization cannot export them for translators. Add both literals to the English translation source.

                PortableImportBanner.Title = CoreTools.Translate("Settings imported");
                PortableImportBanner.Message = CoreTools.Translate(
                    "{0} file(s) were copied. Restart UniGetUI to apply them.", copied);
