test(platform): expand billing coverage to 90% locally

Lifts patch coverage past the codecov 80% gate:

backend:
- Add list_invoices endpoint tests in v1_test.py (default limit, mapped
  payload shape, ?limit=500 → 422 validation, ?limit=24 forwarded).

frontend:
- billing-cards.test.tsx: per-card render assertions for every new card
  (YourPlan, PaymentMethod, Invoices, AutopilotUsage, Balance, AutoRefill,
  Usage, TransactionHistory) with deterministic MSW responses, plus
  Add-Credits dialog open/disabled assertion and AutoRefillDialog
  enable-vs-edit branches.
- billing-hooks.test.tsx: renderHook coverage of every mutation path —
  useBalanceCard.handleSubmit (success/error/no-op), useAutoRefillCard
  save/disable (success/error/short-circuit), useYourPlanCard.changeTier
  (success/error/no-op-on-BASIC) and label fallbacks, plus
  usePaymentMethodCard portal availability.
- helpers.test.ts: pure-JS coverage of formatCents (Intl thousands
  separator + negative prefix), formatRelativeReset (5 branches),
  formatShortDate (3 branches), and EASE_OUT.

Local v8 coverage on the new billing source (cobertura): 90.1%
(201/223 lines).
