Business rule: each user has a daily render limit. Admin-stop refunds the used
charge (not the user's fault); a user's own cancel does not.
- identity: ConsumeRenderChargeAsync / RefundRenderChargeAsync on DailyRemainRenderCount
with lazy daily reset (mig 24: daily_renders_reset_at). Convention: max=0 ⇒ UNLIMITED,
so existing 0/0 users keep rendering until an admin sets a real limit.
- identity InternalController (service-token): POST /v1/internal/render-charge/{consume,refund}
- render-svc: identityclient + on Create consume (block 429 when limit reached, fail-open
on identity outage); on admin Stop refund the job owner; user /cancel unchanged
- compose: IDENTITY_URL for render-svc, ServiceToken for identity-svc
