feat(wiki): randomized admin secret + wiki-anwender group (deployable #0049)

Random Wiki.js admin credentials (SOPS, never displayed) for the config Job to
bootstrap setup non-interactively. Authentik group wiki-anwender (curated readers
of /anwender); admin role = existing authentik Admins. Part of making Wiki.js
fully deployable - no manual setup wizard.
