Implement RegisterPage: load the full public register from the BFF on open, filter
by the search term via /openbaar/register?q=, and show a results table (referentie +
status), a loading indicator, and an empty-state message. Anonymous, same-origin
relative calls. Adds the app-shell spec. All openbaar lint/test/build green.

Scaffolds the anonymous openbaar Angular app (mirrors self-service: standalone +
signals, NL DS via the ui lib, no auth) and adds a failing register-page spec:
loads the public register from the BFF on open, searches by term, and shows an
empty-state message. The stub page renders only the heading, so the list/search/
empty-state assertions fail (red).
