Switch PMS: WP-05 cloud spike

Throwaway test host in AWS Sydney (ap-southeast-2), Tyro Health staging only. Use Tyro's published test patients, test providers and test cards. Use ZZTEST for every reference we set. Never use a real patient.

1. Start a session

Operator: aws lambda invoke … --payload '{"action":"make_code"}' gives a one-time code, valid for 15 minutes.

2. Create a staging transaction

Tyro's own form collects patient, provider and item details. Until Tyro whitelists this domain for staging, expect a CORS error. That error is the evidence that whitelisting is required.
