for better matching of foreign content
The DisplayTitle property was using .NET's CultureInfo.GetCultures(NeutralCultures)
to resolve language display names. Since zh-CN is a specific culture (not neutral),
it would fall back to the base 'zh' code, resulting in generic 'Chinese' instead
of 'Chinese (Simplified)'.
This change adds a LocalizedLanguage property to MediaStream that gets populated
via LocalizationManager.FindLanguageInfo() when streams are retrieved from the
database. This leverages Jellyfin's existing iso6392.txt mappings which correctly
map zh-CN to 'Chinese (Simplified)'.
The same pattern is already used for other localized strings like LocalizedDefault
and LocalizedExternal.
When querying items with recursive=true, items with types from removed
plugins would cause a 500 error. Now these items are skipped with a
warning log instead of throwing an exception.
Fixes#15945
