Fix MSIX installer manifests and mark unverified versions

[Gabriel Dufresne (GabrielDuf)]

This pull request improves how UniGetUI handles and displays package version information, especially when the installed version cannot be reliably determined (for example, if the package was updated outside of UniGetUI). It introduces a new mechanism to detect and visually warn users about unverified or unknown installed package versions, both in package lists and in the package details dialog. The changes also enhance user communication with new tooltips and warning icons, and include a small utility for better version string matching.

User interface improvements for unverified package versions:

• Added a warning icon and tooltip in package lists and details views when a package's installed version is unverified, making it clear to users when the version information may be outdated or unreliable. The tooltip explains the situation and is localized. (src/UniGetUI.Avalonia/Views/SoftwarePages/AbstractPackagesPage.axaml, src/UniGetUI.Avalonia/Views/DialogPages/PackageDetailsWindow.axaml.cs, src/Languages/lang_en.json) [1] [2] [3] [4] [5] [6] [7]

• Updated the package details dialog to display a warning and tooltip for unverified installed versions, including a warning icon and localized message. (src/UniGetUI.Avalonia/ViewModels/DialogPages/PackageDetailsViewModel.cs, src/UniGetUI.Avalonia/Views/DialogPages/PackageDetailsWindow.axaml.cs) [1] [2] [3] [4] [5] [6]

Backend and data model changes:

• Added a new property InstalledVersionIsUnverified to the IPackage interface and set this property in WinGet manager code when the installed version is unknown or unverified. (src/UniGetUI.PackageEngine.Interfaces/IPackage.cs, src/UniGetUI.PackageEngine.Managers.WinGet/ClientHelpers/NativeWinGetHelper.cs, src/UniGetUI.PackageEngine.Managers.WinGet/ClientHelpers/PingetCliHelper.cs) [1] [2] [3] [4] [5] [6] [7]

• Updated PackageWrapper and related view models to expose the new unverified version state and tooltip to the UI. (src/UniGetUI.Avalonia/Models/PackageCollections.cs) [1] [2]

Version string handling improvement:

• Added a utility method to trim trailing zero segments from version strings, improving the ability to match package versions that may be reported in different formats. (src/UniGetUI.PackageEngine.Managers.WinGet/ClientHelpers/PingetPackageDetailsProvider.cs) [1] [2]

🟢 Approval recommended

The changed data paths, UI presentation, localization, version fallback, and edge cases are coherently implemented and covered by targeted tests.

Pull request overview

This PR improves WinGet/MSIX version handling by retrying manifest lookup with normalized trailing-zero versions and surfacing unreliable installed-version data in Avalonia views.

Changes:

• Marks unknown or restored WinGet versions as unverified across CLI, Pinget, and native paths.
• Adds localized warning tooltips/icons to package lists and package details.
• Adds trailing-zero MSIX version fallback with focused tests.
