Add PrivateShop module templates and initial setup files

- Created restricted.tpl for displaying restricted access messages with customizable background options.
- Added index.php files in hook and main template directories to prevent direct access and ensure proper redirection.
- Implemented info.tpl to provide module information and support links, enhancing user experience with promotional content.
- Included necessary CSS styles for the new templates to ensure proper layout and responsiveness.
