/**
 * approve_stock.php — Approve a draft td_stock row (status 0 → 1).
 *
 * Flips status to 1 and calls adjustBalance() so etl_stock_summary
 * reflects the transaction. This is the ONLY place adjustBalance() is
 * called — both auto-approve (on save) and manual approve go through here.
 *
 * Expected $data keys:
 *   id           int     td_stock row id
 *   warehouse    int     warehouse_id (to resolve the dynamic table)
 *   type         string  'in' | 'out' | 'transfer'
