feat(settings): move Outline version to sidebar footer, drop Installation section

Removed the Integrations & Installation category and its lone
Installation section entirely — Outline's server version now shows in
the settings sidebar footer instead, alongside Outpost's own version
(installation.info, fetched once when the sidebar appears). About stays
where it was, unaffected.
