/**
 * Nabeh Integration — Get User Recent Rides
 *
 * Returns the most recent rides for a user (driver or passenger)
 * identified by phone number. Used by the complaint workflow to
 * let the user pick which trip they're complaining about.
 *
 * Auth: X-API-Key header → NABEH_API_KEY
 *
 * Input:
 *   phone (required) — User's phone number
 *   limit (opt)      — Max rides to return (default 5, max 20)
 *
 * Output:
 *   List of rides with id, date, time, price, locations, status, etc.
