and missing Bootstrap styling:

- Add WC gallery modifier classes for zoom/photoswipe JS init
- Fix HTML entity double-encoding in headings (up-sells, cross-sells, related)
- Remove wrong 'is defined' guards on function calls
- Remove duplicate deprecated hooks in dashboard
- Add |raw to brand description HTML filter chain
- Add role="alert" for accessibility, |esc_attr on notification types
- Style mini-cart remove button as Bootstrap btn
- Make shipping form-check class conditional
- Add shop_table CSS reset and gallery opacity fallback
