..F....... [ZBXNEXT-570] implemented the ability to quickly display items on a graph from the latest data page

- It is now possible to select several items on the latest data page and quickly display them all on a single graph. The filter on the latest data page has been changed to allow selecting multiple hosts and host groups at once, as well as filtering by application. The latest data page will now only display values if at least some filter criteria has been selected.
