put the settings section in the url

Five settings pages moved from a `*_SELECTED` global to `/settings/:page/:section`. The
sidebar entry is a react-router `<NavLink>` rather than a button holding the key in its
onClick closure, so a section is linkable, cmd-clickable and gets its active state from the
router; each page renders one `SettingsRoute` guard that canonicalises both the bare route
and a section that does not exist.

Integrations needed more than the shared factory. It builds its own sidebar, and it kept the
Enterprise/Personal tab in a second global — which is why a deep link to a Personal section
could never have worked: the link set the section, the tab stayed on Enterprise, and the
content pane said "Select a section" about a section that existed. The tab is derived from
the section key now.

Also removes the `/settings/resources` menu item (audit M8) and its two locale keys: there
has never been such a route, so it bounced to the catch-all and out to `/`.
