Pull request overview

This PR updates the Settings/General page to safely retrieve version information for both packaged and unpackaged apps. It prevents crashes when running as an unpackaged application by adding a fallback mechanism that reads the version from the process executable, with a final fallback to display "?" when the version cannot be determined.

Changes:

• Added new localized resource string "Settings_GeneralPage_VersionNo" for formatting the version display
• Refactored ApplicationVersion property to use a try-pattern for both packaged and assembly version retrieval
• Added TryGetPackagedVersion method to safely handle packaged app scenarios
• Added TryGetAssemblyVersion method to retrieve version from executable for unpackaged apps

When the executable lacks version information, FileVersionInfo will return zeros for all version parts, resulting in "0.0.0.0" being displayed. Following the pattern used elsewhere in the codebase (e.g., PluginMetadata.cs), consider checking if the version is "0.0.0.0" and returning false in that case, so the fallback "?" is displayed instead of a misleading "Version 0.0.0.0".

Suggested change

	var info = FileVersionInfo.GetVersionInfo(processPath);
	var info = FileVersionInfo.GetVersionInfo(processPath);
	if (info.FileMajorPart == 0 && info.FileMinorPart == 0 && info.FileBuildPart == 0 && info.FilePrivatePart == 0)
	{
	// Executable lacks version information; signal failure so the caller can use the fallback.
	return false;
	}
