Every registration now parks at WachtOpDocumenten first, so each existing block
completes that task (documents received) before expecting Beoordelen/CBGVAdvies.
Adds a timeout block: a registration whose documents never arrive has its P30D
timer fired via the management-API move idiom, and the domain expires it to VERLOPEN.
