feat: Add custom block category "SLM Plus" and improve shortcode blocks - Registered a new block category "SLM Plus" for better organization. - Updated "Forgot License" and "List Licenses" blocks to assign them to the custom category. - Improved block editor previews for both blocks: - "Forgot License" block displays a preview with a form placeholder. - "List Licenses" block displays a preview with a sample list of licenses. - Fixed issues with blocks appearing under "Uncategorized" by ensuring proper category registration. - Ensured unique naming in block scripts to avoid conflicts. - Added clear styles for block previews and frontend rendering in `slm-blocks.css`. - Verified shortcode functionality for rendering licenses dynamically.
