Release version 1.1.2 - Catalog button modification

Enhanced package quantity restriction enforcement by replacing "Add to Cart"
buttons with "View Options" links on catalog pages for products with
quantity restrictions. This prevents customers from attempting to add
restricted products directly from shop/category pages.

Changes:
- Added catalog button modification for restricted products
- Implemented "View Options" button with eye icon styling
- Created has_quantity_restriction() helper method
- Extended CSS loading to all WooCommerce pages
- Added modify_catalog_add_to_cart_button() filter method
- Updated translations with 2 new strings (en_US, de_DE, de_CH_informal)
