Provision TEST_COMPANY and OTHER_COMPANY tenants in SPM

Path 1: Customer Integration API — PUT patient with encounter via Integration API

Path 2: EHR Pipeline — Send HL7 ADT A01 admit message

Path 3: UI-Initiated — Create patient via BFF

Full encounter lifecycle: admit -> transfer -> transfer -> discharge

Idempotency: duplicate patient, duplicate encounter, duplicate note

Multi-tenant: same MRN in two companies -> different tokens

Notes: add note, re-add same content -> deduplicated

BFF: get merged patient view (SPM PHI + Starlink entity)

Verify Starlink/EM received expected calls
