Summary of ChangesHello @leleueri, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed! This pull request introduces a "Post Login Action" capability, enabling Gravitee AM to integrate with external services for additional authentication steps or data enrichment immediately following a user's successful login. This feature allows for a flexible, custom flow where Gravitee AM redirects the user to an external endpoint with a signed JWT, awaits a callback with a validated response, and then proceeds with or denies the login based on the external service's decision. The changes span across core gateway logic, data models, persistence layers, and the management UI, providing a comprehensive solution for extending the login flow with external interactions.

Code Review
This pull request introduces a new 'Post Login Action' feature, allowing for a custom flow after user login. The changes include new backend endpoints, handlers, and model updates to support this feature, as well as UI components for configuration at both the domain and application level. The implementation is quite extensive and covers backend logic, data persistence, and UI.
My review has identified a few areas for improvement:
- A potential bug in the JWT processor creation for EC keys which could impact security validation.
- An issue with data serialization that might lead to incorrect data being stored in the session.
- A minor security concern in the UI regarding URL validation.
Overall, this is a significant feature addition. Addressing these points will improve the robustness and security of the implementation.

Using RSAKeyProcessor to handle EC keys is confusing and likely incorrect. The class name suggests it's for RSA algorithms only. Using it to create a processor for ES256 might lead to signature validation not working as expected or at all for EC keys. Please verify if RSAKeyProcessor is indeed capable of handling EC keys. If not, a dedicated processor for EC keys should be used. The comment // RSAKeyProcessor also handles EC keys seems to be an attempt to justify this, but it adds to the confusion and should be removed or clarified if RSAKeyProcessor is a misnomer.

The data object from the JWT claims can be a complex type like a Map or List. Using String.valueOf(data) will call toString(), which does not produce a valid JSON string for these types. This could lead to data being stored incorrectly in the session. Consider using a JSON library to serialize the data object to a JSON string if it's not a primitive type.

The variable name httpsUrlPattern suggests that only HTTPS URLs are allowed, but the regex pattern ^https?://.+$ also allows HTTP. For security reasons, especially in an authentication flow, it is recommended to enforce HTTPS to prevent potential man-in-the-middle attacks. If HTTP is intentionally allowed, consider renaming the variable to urlPattern to avoid confusion.
