feat: Integrate MorphDeleteButton for sample deletion in PackOrganizer and LibrarySampleGrid

Commit notes

This commit replaces the existing delete buttons in both the PackOrganizer and LibrarySampleGrid components with a new MorphDeleteButton component. The new button provides a more streamlined user experience by managing the deletion state and handling the deletion process for selected samples. The implementation includes state management for deletion status and ensures the UI reflects the current state during operations.
