Pull request overview

This PR converts the dgrid-shim dependency from an external script tag requirement to a self-extracting resource that is bundled directly into the code, similar to how WASM files are handled in the project.

Changes:

• Implemented a new sfxJS plugin to wrap JavaScript bundles as self-extracting resources
• Removed external dgrid-shim script tag dependencies from HTML files across multiple packages
• Eliminated test setup code that manually loaded dgrid-shim before running tests
