Adds an additive bearer-verification path: verify RS256 access tokens against Tessera's JWKS (iss/aud/exp), map sub/preferred_username/email + roles (realm_access.roles, resource_access.<audience>.roles) to the app's identity. Existing auth (API keys / app JWTs / sessions) is unchanged. Issuer + audience are env-configurable. Validated end-to-end against the local sim.
