feat(reui): update ReUI components and documentation to reflect 20 building blocks

- Expanded the ReUI skill description to include 20 free building blocks.
- Updated references in various documentation files to reflect the new count of components.
- Enhanced the data-grid documentation to specify the use of TanStack Table v9.
- Added new component details, including the icon-tile, and clarified usage instructions across multiple files.

This update improves clarity and ensures that all references are consistent with the latest component offerings.
