- Decouple hit area calculation from the rendering effect in
`InventoryItemContainer`.
- Implement a dedicated `hitArea` property to track cell rectangles.
- Update `setupInteractive` to use the container itself as the hit area
with a custom callback.
- Move drag-and-drop logic into a dedicated `setupDnDEffect` method.
- Add `addPreviewRotation` to `InventoryItemState` for cleaner rotation
updates.
- Normalize `previewRotation` to stay within 0-360 degrees.
