Commit notes

This commit updates the BatchEditModal component to include a new optional prop for sample names, allowing for a preview of rename operations. It introduces derived states for displaying affected sample counts and a summary of metadata changes, improving user feedback during batch updates. Additionally, the PackOrganizer and LibrarySampleGrid components are updated to pass the selected sample names to the BatchEditModal, ensuring consistency across the application.
