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.

 - Key required at install: blocks (`@reui/<category>-N`) need a Pro or Ultimate license; Motion Icons (`@reui/icons/...`) and templates need Ultimate.
 
 If an install 401/403s, the license key is missing, invalid, or the plan does not cover that resource (blocks: Pro or higher; icons and templates: Ultimate). Point the user to https://reui.io/account (their key) or https://reui.io/pricing (upgrade).
