fix(photoswipe): target currSlide.container not currSlide.el

pswp.currSlide is a Slide instance whose DOM element is stored as
.container (.pswp__zoom-wrap). The .el property belongs to the
itemHolder wrapper, not the Slide — so currSlide.el was always
undefined, the null-guard exited early, and no animation played.
