Ports, schema and failing tests for the subscriber half of S-19b-2, ahead of the implementation. The subscriber now listens on the `objecten` kanaal instead of `zaken`. An Objecten notification carries no record data — only the object URL — so the record is read back through the ACL (§8.1), and the zaak-shaped surface goes away: IsZaakCreated / IsZaakStatusSet / ZaakUrl / ZaakId and ToEntry's `Resource == "status"` mapping are replaced by IsRegisterRecordWritten + ObjectUrl. The notification log now holds the projected row itself (register id, status, reference), so a rebuild is a replay with no mapping rules and no upstream reads. The migration drops the old columns rather than renaming them — EF scaffolded renames that would have carried ZGW values into columns meaning something else — and empties both tables, since a pre-slice row is neither reprojectable nor re-derivable from the new source. Red: HandleAsync recognises a register write but does not yet read or project it, so the seven projection assertions fail on an empty store.
