Subject: [PATCH] =?UTF-8?q?feat(backlog):=20wave=204=20=E2=80=94=20ops=20r?=
 =?UTF-8?q?eal-data,=20M9=20settlement=20(V24),=20M1=20hall=20assign+quote?=
 =?UTF-8?q?=20(V25),=20roleCode/nav;=20fix=20OTP=20retry=20lockout?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- fix(security): verifyOtp/enrollVerify consumed the challenge BEFORE code verification —
  one mistyped TOTP burned the session and every retry hit "세션 만료" (live incident).
  Now consume only on success, keep challenge for up to 5 failures (OtpChallengeStoreTest)
- SCR-14 ops: congestion from real check-in aggregates, power from utility orders;
  hardware widgets stay as honest "sensor not connected" empty states
- M9 settlement: /api/settlement (dashboard/invoices/generate/issue/payments), V24 invoice
  tables, server-authoritative amounts (ST_Area x rate + VAT), PG-delegation notice, /settlement UI
- M1 hall assign: /api/halls CRUD + period-overlap conflict (409 with details) + rates-v1.0
  auto-quote, V25 idempotent period columns, /halls board UI
- shared: AuthUser.roleCode (JWT rc claim, additive), AdminGuard precise check, AppShell
  placeholder nav wired via event-context builders, /_styleguide dev-only route
