Whats Next? 0.18.5 - Remove duplicate weapon source headers

- Removed the second KEYS / RAID / VOID CORE / CRAFT header row from the weapon area.
- Main Hand and Off Hand now sit directly in the weapon section without duplicate labels behind the equipment rows.
- Reduced weapon panel height and moved weapon rows upward to prevent overlap with WRIST / TRINKET rows.
- Loot state, tooltip, Void Core and item-level logic unchanged.
