Redirect the other www spelling to SITE_ORIGIN, hold roles to the role help and fix the audit findings

SITE_ORIGIN alone decides whether the site is www or not: CanonicalHostSubscriber
sends the other spelling there with 301, cms:site:origin writes the setting, the
system screen shows it. The roles now match the role help (editor: drafts,
publisher: live content, admin: design, settings, users, system). The installer no
longer reopens on an unreachable database, the session cookie follows ADMIN_PATH,
percent-encoded credentials no longer break the container, consent only accepts
same-site decisions, JSON-LD is HTML-safe, own CSS stays in its block, plus the
editor, updater, download and public-output findings from the full review
(ADR 099, ADR 100).
