Fixes#44487
## Summary
Fixed issue where the details pane would display stale information when
navigating from an item with details to an item without details or where
details failed to load.
## Changes
1. **ListViewModel.cs**: Added HideDetailsMessage when SafeSlowInit()
fails to ensure previous details are cleared
2. **InstallPackageListItem.cs**: Added exception handling for WinRT
marshaling errors when accessing metadata.Documentations and
metadata.Tags collections
The fix ensures graceful degradation - if certain metadata collections
fail to load due to WinRT issues, the details pane still displays
available information rather than failing completely.
