fix(m7.1): correct middleware layer order so JwksState is visible

Axum applies layers outermost-first. With the previous ordering
(`Extension(jwks_state)` first, `require_jwt_auth` last), the JWT
middleware ran before the Extension layer attached `JwksState` to
the request, so `request.extensions().get::<JwksState>()` always
returned None and the middleware silently passed through every
request as if Keycloak weren't configured.

Verified end-to-end against the local CERTifAI Keycloak realm:
- no token / bad token -> 401
- active / trial -> 200 read, write reaches handler
- frozen -> 200 read, 402 on writes
- archived -> 410 on every method

The bug was invisible to the unit + integration tests because they
construct the layer stack manually; only the live wiring exhibited it.
