fix(lightbox): clean up on PhotoSwipe init failure

attach! sets every Radix popper to inert=true and installs 5 window-
capture listeners (pointerdown/mousedown/click/contextmenu/keydown).
Cleanup was wired only to PhotoSwipe's "destroy" event, but if .init
or .loadAndOpen threw, that event never fired — leaving the listeners
attached and every popper permanently inert (soft-bricked app).

Wrap init+loadAndOpen in try/catch: on failure synchronously call
detach! to roll back inert + remove listeners, clear the window-global
so mobile/navigation's later .destroy call doesn't act on a broken
instance, and rethrow so the underlying error surfaces.

Verified by stubbing PhotoSwipeLightbox to throw inside .init and
calling preview-images!: caught exception bubbles up, inert restored
to false on a probe popper, and window.photoLightbox is null.
