feat(admin): count revoked html-view capabilities in the logout audit line

The admin forced logout already revoked the user's rendered-HTML
capabilities but recorded only the cookie sessions and web-tab
capabilities it retired. The `user.logout` audit entry now carries
`revokedHtmlViews` next to `revokedWebviews`, and the revocation test
reads it back from admin-audit.jsonl.
