Perfuse v0.1.5

Everything since v0.1.4. Each item was checked against real software; docs/verification.md says what with, and what remains unverified.

Payers (CMS-0057, CMS-0053)

• The four CMS-0057 payer APIs (Patient Access, Provider Access, Payer-to-Payer, Prior Authorization), CARIN Blue Button, PDex and the yearly metrics; Provider Access tokens limited to a provider's Groups.
• Da Vinci CRD 2.2.1 over CDS Hooks, and DTR $questionnaire-package.
• X12 270/271 with CAQH CORE, 276/277 and 834.
• CMS-0053 electronic signatures on 275 attachments: HL7 DSDR, XAdES-X-L with OCSP and RFC 3161 time-stamps, verified by xmlsec1. Fixes three XML-signature faults only an outside verifier caught.

FHIR

• US Core 9.0.0 (USCDI v6): profile claims only on resources checked to conform; DG1 and AL1 converted; race, ethnicity, language.
• v2 to FHIR fixes from community test messages and the HL7 validator, including malformed bundle fullUrls, merges (MRG), PID-2/PID-4, times of birth, embedded PDFs and the sender's MSH-7 offset for bare times. 64 of the 70 public nw-gmsa messages now validate; the other 6 fail only on the senders' own codes.
• Sign-in for hosted FHIR servers: AWS HealthLake (SigV4), Azure Health Data Services (Entra ID), OAuth client credentials.
• SMART Health Links and Cards.

Connectivity and migration

• AWS SQS and S3 sources, SQS and SNS destinations, Glacier and Athena archives; AMQP 1.0 (Azure Service Bus, RabbitMQ 4, ActiveMQ) and Azure Blob Storage.
• Migration from Mirth, OIE and BridgeLink: whole backups, code templates, more connectors.

Fixes

• The channel builder saves the form as it stands, not a preview up to 400 ms old.
• The Fleet view fits a phone screen.
