+/**
+ * POST /api/admin/billing/orgs/[orgId]/payment-mode
+ *
+ * Phase 9b-2. Admin-only override of an org's billing mode:
+ *   - payByInvoice (boolean) — flip the customer's account to
+ *     bank-transfer billing. Auto-charge is skipped entirely for
+ *     these orgs; they receive the regular issued-invoice email
+ *     and pay manually. Switching ON also implicitly stops
+ *     attempting card charges even if a saved card exists.
+ *   - autoChargeEnabled (boolean) — pause auto-charge without
+ *     committing to pay-by-invoice. Useful during disputes or
+ *     billing investigations.
+ *
+ * Either flag may be omitted; the endpoint only writes what's
+ * provided. Returns the updated config.
