fix: PHP errors and clean up error_log statements

- Fixed redirect_wc_pages_to_spa: added spa_mode check (only redirect when 'full')
- Fixed PHP fatal error: use get_queried_object() instead of global $product
- Removed all error_log debug statements from codebase
- Fixed broken syntax in PaymentGatewaysProvider.php after error_log removal
