Uplink store interface searchable with a searchbar. (#24287)

* Can now search the uplink store interface with a searchbar.

* Search text updates no longer send server messages. Persists listings locally.

* Formatting fixes and tidying.

* Added helper method to get localised name and description (or otherwise, entity name and description) of store listing items.

* Update Content.Client/Store/Ui/StoreMenu.xaml

* Review change; moved localisation helper functions to their own class.

* Prevent thread-unsafe behaviour as-per review.

* Remove dummy boxcontainer
