Release version 1.2.5 - Parent product default pricing and UI enhancements

Browse Source 
Added:
- Parent product default pricing for variable products - set tier/package pricing once on parent, variations inherit unless overridden
- Hide empty table headers in admin until pricing rules are defined

Technical:
- Added parent fallback logic to get_tier_price() and get_package_price() methods
- Created helper methods get_packages_with_fallback() and is_restriction_enabled() in cart class
- Updated all cart methods to support parent product defaults
- Added CSS :has() selectors to hide table headers when tbody is empty
- Fixed cart pricing calls to pass correct product ID for fallback resolution
