BREAKING CHANGE: Variable products now supported in composable products.
Changes:
- Modified get_available_products() to detect variable products
- Variable products now expand to show all available variations
- Each variation is checked individually for stock and purchasability
- Simple products continue to work as before
This allows customers to select specific variations (e.g., "T-Shirt - Red - Large")
instead of just seeing "T-Shirt" which wasn't selectable.
Fixes the issue where products weren't showing because all products
in the category/tag were variable products.
