test: cover self-registered email token parsing

[martinothamar-agent]

Description

Adds a real TT02 selfregistered-email token without a username claim to the Can_Parse_Real_Tokens test table and records its parsed authentication snapshot.

This verifies the token shape reported in Altinn/altinn-studio#19989 continues to parse as a self-identified Authenticated.User with a nullable username.

Verification

• dotnet build solutions/All.sln -v m
• dotnet test solutions/All.sln -v m --no-restore --no-build

Summary by CodeRabbit

• Tests
  • Added coverage for authenticating self-identified users with self-registered email credentials.
  • Added a verified real-world token fixture, including identity, claims, profile, access, representation, and instantiation permissions.
  • Confirmed successful parsing of the new authentication token type.

📝 Walkthrough

Walkthrough

The authentication tests add a verified self-registered-email token fixture. The token is classified as SelfIdentifiedUser and is expected to parse successfully.

Changes

Self-identified token authentication

Layer / File(s)	Summary
Token fixture and parsing coverage test/Altinn.App.Core.Tests/Features/Auth/AuthenticatedTests.Can_Parse_Real_Tokens_type=SelfIdentifiedUser_EvhP.verified.txt, test/Altinn.App.Core.Tests/Features/Auth/AuthenticatedTests.cs	Adds authentication metadata, JWT claims, party details, profile data, permissions, and parsing expectations for a self-identified user token.

Estimated code review effort: 1 (Trivial) | ~5 minutes

Merge Risk: 🟠 High · up to b6cf0

The PR adds a real bearer token containing personal identity data in two test artifacts and ties the fixture to an expiration time on August 14, 2026; this creates a security/privacy exposure and can cause the test to fail after expiration, so it is not merge-ready until a sanitized, safely expired fixture replaces it.
