Integrate the StanzaAPI pharma-dscsa micro-API.

Endpoint: POST https://api.stanzaapi.com/pharma-dscsa/api/v1/dscsa/validate-barcode
Auth header: x-api-key: YOUR_API_KEY
Content-Type: application/json
Request body:
{
  "rawBarcode": "010030123456789621123456789012\u001d1726083110LOT99881"
}

Rules:
- Send the request with a 2-second timeout.
- Parse the standard envelope { success, data, meta: { latency_ms, version } }.
- On failure, read { success: false, error, code } and branch on the code.
- Do not retry 4xx responses; surface the error code to the caller.
- Treat invalid-but-well-formed payloads as HTTP 200 with data.valid === false.
