/**
 * Netlify scheduled function — daily reconciliation of Helcim payments.
 *
 * Calls the protected Nitro route `/api/internal/reconcile-payments` with the
 * shared-secret header. Heavy lifting (Mongo queries, Helcim API calls, retry
 * logic) lives in the Nitro handler so it can use auto-imported utils.
 *
 * Required env (set in Netlify dashboard):
 *   - URL              (set automatically by Netlify)
 *   - RECONCILE_TOKEN  (must match NUXT_RECONCILE_TOKEN in Nitro runtime config)
 *
 * Schedule: @daily (00:00 UTC). Also pinned in netlify.toml.
