Introduced a new endpoint for bulk filling collection posters, allowing for automatic assignment of posters to collections without existing images. Updated the DeleteShowCommand to include an option for cutting shows from future airings, enhancing the deletion process. Refactored related components and API calls to support these features, ensuring a seamless user experience. Additionally, updated localization strings to reflect the new functionalities and adjusted tests to verify correct behavior.
Implemented several unit tests to validate the behavior of dynamic group modes, including the preservation of pinned items when switching to dynamic mode, the dropping of exclusions when reverting to static mode, and the default pinning of new elements in dynamic groups. Additional tests ensure that exclusions are correctly applied and removed, and that static groups refuse exclusions. These tests enhance the coverage and reliability of the group management functionality.
