feat: the admin settings cards read as menus: each a titled group of rows with one short line, status first, failures in words (M503 #5607)

Indexers and clients, searching, missing files, Lidarr's neighbours, AcoustID, fingerprinting, loudness, outgoing email's schedule, public address and proxies move from paragraph cards to SettingsGroup and SettingRow. Switches are role="switch". Also fixes the two type errors run 9023 found: the Lidarr test result is narrowed before its lists are read, and the tag-source save mock carries version_bumped.
