Live location share - focus on user location on list item click (PSG-609) (#9051)

* extract preventDefaultWrapper into utils

* add click handling to beacon list item

* add click handling to dialog sidebar

* focus in on beacons when clicked in list

* stylelint

* fussy import ordering

* test beacon focusing in beaocnviewdialog
