refactor(nav): lift navigation + history into NavigationProvider

Move page/channelView/ytSearch and the history/popstate/title effects out of the
App god component into a new NavigationProvider (split state/actions contexts so
the memo'd VideoCard doesn't re-render on a page/channel switch). App consumes it
via useNavigation/useNavigationActions but still passes the props down for now;
the consumer migration that removes the prop-drilling follows.
