test(backend): type-state Aanvraag builder, illegal fixtures unrepresentable (WP-70)

RuleTests/OpenZaakZaakSourceTests hand-built Aanvraag fixtures by initializer,
keeping Submitted/Referentie/SubmittedAt/BesluitStatus consistent by hand. A
type-state builder (Given.Concept().Submitted().Decided()) makes an illegal
sequence a compile error instead, and delegates the toelichting-required rule
to the real BeoordelingRules so it can't drift from production. Adds
BesluitLifecycleTests covering the WP-68 besluit invariants end to end.
