Subject: [PATCH] feat(billing): Stripe-backed billing engine (dark-launched)

Add a lazy/guarded Stripe client (boots without keys), Invoice/Payout schemas, per-currency Price.stripePriceIds, and a BillingService deriving partner/platform summaries, invoices and a partner-cut payout ledger. Partner and operator billing controllers plus a signature-verified Stripe webhook (Fastify raw body). Frontend: partner and operator billing pages and the operator tenant billing/audit tabs on real data. Gated behind new_billing_engine and BILLING_STRIPE_ENABLED; live money paths stay off until keys are set.
