Fixed an issue within the paging implementation of the CategoryModifiedEventListener, SingleProductIndexedEventListener, and InitializeBulkOperationItemsListener.
Previously, the Pageable request was stuck at page 0 during bulk operations parsing product memberships and auto-included categories, resulting in an infinite loop when the number of items exceeded the initial batch size. The pageable objects are now correctly advanced (e.g., searchPageable = searchPageable.next()) to appropriately traverse search results and auto-included categories. New comprehensive test suites were also added to validate correct paging behaviors.
