Release version 1.1.3 - Cart quantity visibility fix

Fixed persistent cart quantity input visibility issues for products with
package quantity restrictions. Enhanced implementation ensures quantity
inputs are properly hidden in both main cart and mini-cart/sidebar.

Fixes:
- Cart quantity inputs now properly hidden with increased filter priority
- Mini-cart quantity inputs correctly replaced with read-only text
- Added fallback CSS injection to handle theme/plugin conflicts
- Enhanced DOM targeting with data attributes and multiple CSS selectors

Technical Changes:
- Increased filter priority to 999 for woocommerce_cart_item_quantity
- Added woocommerce_widget_cart_item_quantity filter for mini-cart support
- Added add_cart_quantity_css() method for dynamic CSS injection
- Added maybe_hide_mini_cart_quantity_input() method
- Enhanced quantity spans with data-product-id attribute
- Added wc-tpp-restricted-qty CSS class
- Implemented sibling (+) and general sibling (~) CSS selectors

Updated Files:
- includes/class-wc-tpp-cart.php (enhanced with mini-cart support)
- wc-tier-and-package-prices.php (version 1.1.3)
- composer.json (version 1.1.3)
- CHANGELOG.md (v1.1.3 section)
- All translation files (.pot, .po, .mo) updated to version 1.1.3
