docs: add Focus Mode section and group-from-selection video

Document Focus Mode on the Control Center overview (right-click a node
and choose Focus, or select it and press F) with two screenshots, and
move the F shortcut prose there from the Draft Mode page. Add a
recording of creating a group from a multi-peer selection to the
Draft Mode page. New media compressed like the rest.
