Replaces the hardcoded DocumentStore.DemoOwner and the static ZgwOptions
UserId/UserRepresentation with one per-request CallerIdentity, resolved by a
pluggable IIdentityProvider (StubIdentityProvider reads X-Role/X-Subject
today; a real OIDC/DigiD provider swaps in without touching any consumer).
- Domain/Authorization/{CallerIdentity,IIdentityProvider,StubIdentityProvider}.cs
+ a resolution middleware in Program.cs, right after correlation-id.
- Authz.ResolvePrincipal(ctx) keeps its signature (now reads ctx.Caller().Role),
so its ~15 call sites needed no changes.
- Every endpoint that passed DocumentStore.DemoOwner to a store now passes
ctx.Caller().Bsn.
- ZgwTokenProvider gains Mint(CallerIdentity) alongside the original Mint()
(kept for calls not tied to one citizen); ZgwHttpClient threads an optional
caller through to pick the right overload.
- IZaakSource gains ListMyCases(caller, now) — the citizen-scoped read
OpenZaakZaakSource backs with ZGW's rol__...__inpBsn filter. GET /applications
now routes through it instead of ApplicationStore directly, closing the last
"reads a static store" gap for a citizen-facing endpoint.
Backend 159/159 tests (+8, incl. an HTTP-level two-identity scoping proof),
npm run ci green, no api-client drift.

The two highest-value OpenZaak roadmap gaps, each written self-contained (a "current
state" handoff section) so a fresh session can execute from the file + repo alone:
- WP-53: replace the stubbed owner/BSN with a real per-request CallerIdentity
(pluggable stub, not DigiD), threading it into Authz, the ZGW JWT user claims, and
a citizen-scoped read (rol__…__inpBsn). Production-blocking for a real deployment.
- WP-54: a separate docker-compose OpenZaak + scripted bootstrap + opt-in
Category=Integration test — makes 50/51/52 developable against a live instance
instead of only fixtures; kept out of the default gate.
