Release version 1.1.2 - Catalog button modification

Browse Source 
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)

### Product Page (v1.1.0)
- ✅ Quantity field automatically hidden when restriction enabled
- ✅ "Choose a package size below" notice displayed
- ✅ Visual package selection with highlighted states
- ✅ JavaScript validation prevents form submission without package selection
### Add to Cart Validation (v1.1.0)

### Settings

## Use Cases
### Scenario 1: Bulk-Only Sales
Enable restriction globally to sell products only in bulk quantities.
**Example:**
- Package 1: 100 units at $500
- Package 2: 250 units at $1,100
- Package 3: 500 units at $2,000
Customers can only purchase these exact quantities on both product page and in cart.
### Scenario 2: Sample Packs
Create fixed sample packs with no custom quantities.
**Example:**
- Starter Pack: 10 items
- Trial Pack: 25 items
- Full Pack: 50 items
Quantity cannot be changed in cart - customers must return to product page to select a different package.
