fix(ui): prevent accidental hover selections in context menu

Add logic to temporarily disable hover-based selection when context menu items change, preventing unintended selections during dynamic updates.

Also introduce stable empty array references- Previously, the empty arrays were causing the props to change, causing a continuous render loop while the @ContextMenu.tsx was open

Fixes: #2104
