Idempotency

Mutating `/v1` requests should include an `Idempotency-Key`. The API records the request body hash so retries can return the same result instead of creating duplicate operations.

curl -X POST "$NITY0X_URL/v1/payments" \
  -H "Authorization: Bearer $NITY0X_API_KEY" \
  -H "Idempotency-Key: order_123_create_payment" \
  -H "Content-Type: application/json" \
  -d '{"amount":"25","chain":"tron"}'

Reusing a key with a different body is treated as an idempotency error. Use stable keys derived from your own order or payout attempt IDs.
