Integration-branch revision with the Fastly and Axum parts of EZI-1 #490

Summary

Integration-branch revision with the Fastly and Axum parts of EZI-1.

Behavior

EdgeZero keeps the integration branch rc/identity for this work (DEC-5, #495). Each integration point is a commit on it that Trusted Server main pins by SHA until EdgeZero releases the work; there are no tags. The branch moves only forward, by merges, and is never force-pushed. R1 is the first commit that carries #275 through #439, so Axum production serving does not wait for the record contract. R1b adds EZI-2a and EZI-2b. R2 adds the Fastly and Axum parts of EZI-1. R2b adds EZI-3, #90, #92, the JA4 accessor (#283) and Axum's geo binding (EZI-4a), so providers never wait on JA4. Together R1, R1b, R2 and R2b cover Fastly and Axum. R3 adds the Cloudflare parts of EZI-1 to EZI-4, and R4 the Spin parts. EZI-2p and EZI-5 follow the MVP (DEC-15).

Acceptance criteria

• Each integration point is a commit on rc/identity that Trusted Server main pins
• R1, R1b, R2 and R2b contain no Cloudflare or Spin part
