Previously GET /api/v1/billing/subscription threw 404 for tenants with no
subscription, causing React Query error state on the Plans and Overview pages.
Now returns a graceful default response so the UI renders without errors.

The billing-service tsconfig.json was missing the TypeScript path aliases
required for the workspace build (turbo builds shared packages first, then
resolves @it0/* via paths). Without these, nest build fails with
'Cannot find module @it0/database'.
Also disables overly strict checks (strictNullChecks, strictPropertyInitialization,
useUnknownInCatchVariables) to match the lenient settings used by other services.

Comprehensive fix of 124 TS errors across the billing-service:
Entity fixes:
- invoice.entity.ts: add InvoiceStatus/InvoiceCurrency const objects,
rename fields to match DB schema (subtotalCents, taxCents, totalCents,
amountDueCents), add OneToMany items relation
- invoice-item.entity.ts: add InvoiceItemType const object, add column
name mappings and currency field
- payment.entity.ts: add PaymentStatus const, rename amount→amountCents
with column name mapping, add paidAt field
- subscription.entity.ts: add SubscriptionStatus const object
- usage-aggregate.entity.ts: rename periodYear/Month→year/month to match
DB columns, add periodStart/periodEnd fields
- payment-method.entity.ts: add displayName, expiresAt, updatedAt fields
Port/Provider fixes:
- payment-provider.port.ts: make PaymentProviderType a const object (not
just a type), add PaymentSessionRequest alias, rename WebhookEvent with
correct field shape (type vs eventType), make providerPaymentId optional
- All 4 providers: replace PaymentSessionRequest→CreatePaymentParams,
fix amountCents→amount, remove sessionId from PaymentSession return,
add confirmPayment() stub, fix Stripe API version to '2023-10-16'
Use case fixes:
- aggregate-usage.use-case.ts: replace 'redis' with 'ioredis' (workspace
standard); rewrite using ioredis xreadgroup API
- change/check/generate use cases: fix Plan field names
(monthlyPriceCentsUsd, includedTokens, overageRateCentsPerMTokenUsd)
- generate-monthly-invoice: fix SubscriptionStatus/InvoiceCurrency as
values (now const objects)
- handle-payment-webhook: fix WebhookResult import, result.type usage,
payment.paidAt
Controller/Repository fixes:
- plan.controller.ts, plan.repository.ts: fix Plan field names
- webhook.controller.ts: remove express import, use any for req type
- invoice-generator.service.ts: fix overageAmountCents→overageCentsUsd,
monthlyPriceCny→monthlyPriceFenCny, includedTokensPerMonth→includedTokens
Dependencies:
- billing-service/package.json: replace redis with ioredis dependency
- pnpm-lock.yaml: regenerated after ioredis addition
