fix(armor): correct Frontier piece names to match EU exactly 

- Frontier Helmet, Adjusted (M)
- Frontier Harness, Adjusted (M)
- Frontier Arm Guards, Adjusted (M) - both arms
- Frontier Gloves, Adjusted (M) - both hands
- Combined leg piece: Thigh+Shin+Foot Guards

Note: Full separation of Thigh/Shin/Foot would require additional armor slots
