Added a functional preview of the player's appearance to the Closet UI
Related to FRPG-308
The Closet UI is temporarily initialized using static lists of VanityDTOs for the player's current and owned vanities. It will need updated to retrieve these from the respective methods in PlayerClient when they are built. Also, the player preview currently only supports hat and body vanities until the other vanity factories are merged in.
