ehoandClaude Sonnet 5 b937e55ad3 test: close illegal-state escape hatches in spec type-safety (WP-71)
ESLint blanket-exempted every *.spec.ts from the any ban, and no gate
type-checked spec files at all (ng test is transpile-only), so a wrong
cast in a test could never fail the build. 76 `as any` + 12 `as
Extract<>` state-narrowing casts in the three biggest wizard specs read
one variant's fields off a whole-union value: if the reducer returned
the wrong variant, the assertion silently read undefined instead of
failing.

expectTag(state, tag) (libs/shared/src/testing/expect-tag.ts) asserts
and narrows in one call, replacing every one of those casts. Removes
the spec-file any exemption, adds `npm run typecheck` (tsc --noEmit
over each project's tsconfig.spec.json) to CI, and forbids production
code from importing libs/shared/src/testing via dependency-cruiser.
Backend: AanvraagBuilder now models ZaakUrl (closing the last
post-Build() mutation) and guards AtStep; null-forgiving `!` on
endpoint assertions replaced with Assert.NotNull so a null DTO fails by
name, not NullReferenceException.
