added cors configuration

[sacrana0]

Closes #1997

Summary by CodeRabbit

• New Features

  • Added configurable allowed-origin support for cross-origin requests.
  • Allowed origins can be set through application configuration or an environment variable.
  • Configured origins are now applied consistently to cross-origin request handling.

• Bug Fixes

  • Improved configuration handling by prioritizing the environment setting, then the YAML value, with an empty fallback when neither is provided.
  • Corrected error handling for invalid ID-token requests.

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits within each organization.

For paid Pro and Pro+ reviews, CodeRabbit uses a developer's included PR review attempts over the past 7 days to set the current hourly allowance. At typical activity levels, the full plan allowance applies. Higher sustained activity can lower the allowance until earlier attempts leave the 7-day window.

Please refer docs for additional details.

Walkthrough

The service reads AllowedOriginRegex from environment or YAML configuration, converts it into a ThunderID OriginConfig, and passes it during engine creation. Tests cover precedence, empty defaults, and a JWE error assertion fix. The ThunderID dependency is updated.

Changes

CORS origin configuration

Layer / File(s)	Summary
Resolve allowed-origin configuration esignet-service/internal/config/app.go, esignet-service/internal/config/app_test.go	AppConfig adds the allowed_origin_regex field. applyDefaults uses the environment variable, then YAML, then an empty value. Tests cover these cases.
Pass origin configuration to ThunderID esignet-service/cmd/esignet/main.go, esignet-service/go.mod	Startup creates an OriginConfig from the configured regex and passes it to the ThunderID engine. The dependency and replacement use the newer pseudo-version.
Correct JWE error assertion esignet-service/internal/engine/actor_provider_test.go	The test checks the error code only after it confirms that the service error is non-nil.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to b4e0f

The change has no identified production-impacting risk. One localized test assertion should be bound to its subtest for clearer failure handling, but no actionable merge-blocking risk remains.

Poem

Regex enters through config’s gate,
ThunderID receives its state.
YAML and environment agree,
Tests guard each possibility.
Origins start correctly.

Check name	Status	Explanation	Resolution
Linked Issues check	⚠️ Warning	The changes configure an allowed-origin regex, but they do not add the required Nginx methods, headers, or origin mapping from issue #1997.

Out of Scope Changes check	⚠️ Warning	The actor_provider_test.go assertion fix is unrelated to the CORS objective and is an out-of-scope change.	Move the unrelated actor_provider_test.go assertion fix to a separate pull request.
