feat-ui - The Return of the Identify

[mattsigal]

Pull Request

Summary

One of the features I loved in base Jellyfin was to Identify media that might have the wrong meta-data attached to it. This PR incorporates a Jellyfin-style Identify metadata function that allows administrators to identify and update metadata for Movies, TV Shows, and Collections via item context menus and detail page admin controls. Interface improves upon Jellyfin's UI (shows searchable fields with keyboard entry points, that can also be populated from the currently detected meta-data, and is themed) and was designed to be TV-friendly with full d-pad traversal implementations included.
