fix(studio): a snap the saved clip would miss no longer moves it (#5006)

* fix(studio): a snap the saved clip would miss no longer moves it

* test(studio): walk that a deep-zoom move lands where it shows, with no jump on release

* test(studio): the release walk waits for the saved start, not the drag's own

* test(studio): find the drag landing slot by its test id
