Add bulk poster filling endpoint and enhance show deletion options

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.
