Fix: Search Box Implementation for keyboard shortcut (#5140)

* refactor: Move searchbox preference to the searchboxstore

* fix: Ensure that the search box uses the preferred implementation.

* polish: Open at current mouse location.

* [test] add basic unit tests for searchBoxStore

* types/testing: Tweak the types and setup for the searchBoxStore tests
