Whats Next? 0.18.6 - Ring/Trinket slot distribution

- Ring 1/Ring 2 and Trinket 1/Trinket 2 are now allocated per source and per priority.
- The first HIGH/BIS item fills row 1; the second fills row 2.
- Keys, Raid, Craft and Void Core each allocate independently.
- Prevents multiple tracked rings/trinkets from overlapping in one Equipment Loot Test cell.
- No changes to tracked loot data, tooltip logic, item level preview, obtained state or Void Core independence.
