#244: mode marked — flag profile-violating configuration in the UI

Every catalog-listed control on the admin surfaces carries an accessible
deviation marking in mode marked: text + icon under the control (never
colour alone), part of the control's accessible description
(aria-describedby), i18n de+en. The check runs against the CURRENT
control value, so a violating choice is marked before saving. Covered
controls: registration mode, new-page classification, upload policy,
SVG policy, the four master switches (api/mcp/feeds/plugins), the legal
texts (violating while empty), and the Nextcloud backup toggle on the
system panel. The profile card (#243) gains the warning summary and the
hardening-guide reference. e2e: new vs-nfd-marking pack (marked half in
CI — the e2e api now runs VS_NFD_MODE=marked, which also puts the
marked state into the a11y admin scan; off half in local default runs;
both halves verified live). hidden/enforced follow in #245/#246.
