Quality of Life by Shmargus

### Bug Fixes

- **Fixed iLevel Difference Threshold not saving properly** - The threshold input field now correctly saves values when you press Enter or click away. Invalid values are automatically reset to the default (30).

### New Features

- **Use Equipped Slot iLevel** - New option in the Gear tab that compares items against your currently equipped item in that slot instead of your average item level. This is useful when you have one slot significantly higher than your average and want to sell outdated items for that specific slot.
  - For rings and trinkets, it compares against the lower of your two equipped items
  - Falls back to average item level if the slot is empty

### Changes

- **Maximum Quality to Sell** - Default changed from Poor to Common, and Poor quality removed from the dropdown. Grey items are already handled by the regular "Auto Sell Junk" feature, so the Low iLevel Gear Selling feature now starts at Common quality.

- **Removed "Prioritize Uncollected Transmog"** - This option has been removed from the Quest Rewards automation. Game automatically gives transmogs on quest completion anyway.

### Quality of Life

- Hint text below the iLevel threshold dynamically updates to reflect whether you're comparing against your average or equipped slot item level.
