This update improves how shared website and report templates are loaded by processing related template calls in batches. It should make template-heavy pages and report editing more efficient while keeping the user experience unchanged.

Demo product attribute data has been reorganized so it can be shared from the core product area instead of being duplicated across related features. This makes sample data easier to maintain and keeps product, rental, manufacturing, and barcode demo examples more consistent.
