Refactors inventory management and UI update logic.

- Improves inventory data handling by introducing a bucket-based system for category management.
- Streamlines UI updates by implementing a queued refresh mechanism to prevent redundant calculations
- Enhances item filtering by using pre-calculated item lists.
- Fixes an issue with autosizing and layout recalculations to ensure responsiveness and correct display.
