Summary of Changes

Hello @dev-marek, 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 significantly refactors the management and retrieval of portal navigation items. It introduces a more robust and flexible architecture by centralizing navigation item queries into a dedicated service and use case, while also enhancing the domain models for better type safety and hierarchical representation. The changes aim to improve the maintainability and extensibility of the portal's navigation system.

Highlights

• Repository API Refinement: The PortalNavigationItemRepository interface has been updated to remove the organizationId parameter from the findAllByAreaAndEnvironmentId method, streamlining queries to be environment-specific for a given area.
• Repository Implementations Alignment: Both JDBC and MongoDB implementations of PortalNavigationItemRepository have been adjusted to match the updated API signature, ensuring consistency across persistence layers.
• Domain Model Enhancements: The PortalNavigationItem class is now sealed, restricting its direct subclasses to PortalNavigationPage, PortalNavigationLink, and PortalNavigationFolder, which are now final. A parentId field has also been added to PortalNavigationItem for hierarchical structuring.
• New Query Service for Portal Navigation Items: A new PortalNavigationItemsQueryService interface and its PortalNavigationItemsQueryServiceImpl implementation have been introduced to provide dedicated methods for retrieving portal navigation items, including finding by ID, parent ID, and top-level items by area.
• New Use Case for Listing Navigation Items: A ListPortalNavigationItemsUseCase has been added, leveraging the new query service to fetch portal navigation items. This use case supports listing top-level items or children of a specific parent, with an option to recursively load all descendants.
• Repository-to-Domain Model Adapter: A new PortalNavigationItemAdapter has been created to facilitate the conversion between repository-level PortalNavigationItem entities and the core domain models, handling specific configurations for page and link types.
• Removal of PageExistsSpecification: The PageExistsSpecification.java file has been removed, indicating a refactoring or simplification of page existence validation logic.
• Comprehensive Testing Infrastructure: New in-memory repository and query service implementations, along with dedicated test fixtures and unit tests, have been added to thoroughly validate the new portal navigation item listing functionality.

Code Review

This pull request introduces a use case for listing portal navigation items, along with significant refactoring of the PortalNavigationItem model and its corresponding repository. The changes are generally positive, making good use of modern Java features like sealed classes. However, there are several areas for improvement. The new query service implementation has performance issues due to in-memory filtering instead of leveraging database queries, which could be problematic at scale. Additionally, the adapter for converting between repository and domain models could be made more robust and efficient. My review includes specific suggestions to address these points.
