Feature: #97347 - Allow keyboard navigation in live search

See Issue #97347

Description

It is now possible to select results in the live search using the arrow keys up/down and enter/tab to open the selected result. On top the input field stays focused after a record selected so a user can quickly search and open any record from the result list without using a mouse.

Previously it was not possible to use the keyboard to navigate through the search results of the live search.
