Added new Hephaestus uniforms (#20812)

This adds a fair bit:
- Splits the Hephaestus security and ERT/military uniform, since the
security uniform's description doesn't really match that of their
private military (and there is the possibility both may meet in a single
round)
- Adds a Hephaestus-colored captain's cap and gloves, which fits with
their current uniform
- Updates the cyclops uniforms to include rolled states.
- Added a Hephaestus physician's uniform and surgical outfit, and mapped
those into the ERT ship.
