Niek Otten 751ca006a7 test(bff): endpoints, JWT auth and public-safe projection (refs #8)
Failing tests for the BFF walking-skeleton endpoints:
- POST /self-service/registrations rejects missing/malformed/wrong-key/expired
  tokens (401) and, with a valid digid token, forwards the bsn to the domain and
  returns 202 (WebApplicationFactory + a local test signing key, ADR-0010).
- GET /openbaar/register serves public-safe rows anonymously (never the bsn) and
  filters by q.
- OpenbaarProjection.PublicView (pure) filters by id and maps to id+status only.

Endpoints and PublicView are stubs so the tests compile and fail on their
assertions; the green commit implements them.
