Show when each extension was last updated

MCP, skill and tool rows in Settings say "Updated 5m ago" beside how
they're reached and who gets them. updated_at now means a change to an
extension's settings (an edit, or any Access save): runs, connections and
MCP syncs keep their own last_checked_at / last_synced_at and no longer
touch it.
