Issue number: closes #8627

Summary

Changes

VPC Lattice sends the Roles Anywhere certificate fields in requestContext.identity in camelCase (x509IssuerOu, x509SanDns, x509SanNameCn, x509SanUri, x509SubjectCn), but vpcLatticeEventV2Identity and VpcLatticeV2RequestContextIdentity looked up four of them with a capital X. Only x509_san_dns used the right key.

This changes the keys in the data class and the aliases in the parser model to match the V2 event structure, and adds a test for each that sets all five fields. Both tests fail on develop.

User experience

Before: x509_subject_cn, x509_issuer_ou, x509_san_uri and x509_san_name_cn were always None for requests authenticated with IAM Roles Anywhere.
After: they return the values VPC Lattice sends. Test events that used the capitalized keys no longer populate these fields, since those keys don't match what the service sends.

Thanks @LuisFigueroaG, third one from you this cycle! I checked the V2 event in the VPC Lattice docs and the five fields are indeed lower-case x509…, so only san_dns could ever work. Ran the data classes and parser suites and probed both casings, all good. Approving, this goes out in 3.38.0, no need to rebase, I'll handle it and you'll get the credit in the release notes.
