#245: mode hidden — hide profile-violating options, mark the hiding

In hidden (and later enforced) mode, catalog-listed controls whose only
purpose is enabling a violation are not rendered while their saved value
is compliant (the four master switches, the Nextcloud backup block);
value-listed selects keep only their compliant choices (registration
mode, new-page classification, upload policy, SVG policy). Every
affected section shows one accessible policy note (i18n de+en) so
policy is distinguishable from missing features. A value that was
already violating is surfaced exactly like in marked — never silently
hidden. The API stays unchanged; enforcement is #246. e2e: hidden half
of the marking pack (rows disappear, note visible, already-violating
row stays marked, axe WCAG A/AA clean) — verified live locally; CI runs
it against a second api (VS_NFD_MODE=hidden, same database) behind its
own static server.
