Fix single product layout conflicts with WooCommerce CSS

WooCommerce's layout CSS fought Bootstrap's grid in three ways:

1. Float-based two-column layout (width: 48% + float) on div.images
   and div.summary squeezed content inside our col-lg-6 columns.
   Reset with float: none; width: 100%.

2. Nested content wrapper (.container + #primary + <main>) from
   woocommerce_output_content_wrapper doubled up on the parent
   theme's existing .container. Remove the hooks entirely.

3. Sale badge (position: absolute; top: -.5em; z-index: 9) escaped
   the image column and blocked breadcrumb clicks. Override to
   top: 0.5em; z-index: 1 and use gx-* (horizontal-only gutters)
   to avoid negative margin-top on the .row.
