What's Next? 0.17.6

Equipment Loot Test update:
- Added Blizzard-native ITEM LEVEL selector with all current loot-track item levels.
- Equipment rows are now grouped visually by source instead of priority:
  1. KEYS / Ключи
  2. RAID / Рейд
  3. VOID CORE ROLL / Бросок Сердечника Бездны
- Void Core Roll is reserved as an empty future category.
- Existing item priority remains available from the item context menu.
- Old Loot Browser and My Loot screens are unchanged.
