Admin polish after the move

I walked the app after the move and fixed three bugs: release previews picking up the artist photo, a Connect tile showing the wrong icons, and sign-in links landing on the sign-up tab. Shows got a verified place search and a proper date picker, and every editor shares one layout. Gallery playback works on a phone again, preloads the next slide, and respects reduced motion. Artists can drag their links into order, limits follow the plan, and Settings explains the free builder plan.
