feat(billing): partner payout-ledger generation (worker + operator trigger)

Add BillingService.generatePayouts: idempotent per-partner/month/currency snapshot of gross MRR x marginPct into Payout rows (never rewrites a paid row), plus platformPayouts(). A PayoutWorker generates the current month daily (and on boot; PAYOUTS_AUTOGEN=false to disable). Operator endpoints GET /billing/payouts + POST /billing/payouts/generate, an operator payouts ledger table with a Generate button, and the proxy routes. The partner Payouts tab now shows real data.
