Adds an Idris Incorporated dress uniform (#20688)

Adds a generic Idris dress to the loadout, exclusive to Idris
Incorporated characters, sprited by the very talented Comet Blaze on
discord! I'd mostly see this being worn by service staff, including
ICSUs and IAUs, which currently don't have a very good generic uniform
to wear.

Mapping changes are adding the same dress to the Idris Cruiser offship.
