and missing Bootstrap styling:

- 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
