fix: unlisted-recipe share link wrongly warned it wouldn't work (v0.28.3)

The public /r/{id} route allows any visibility except "private", so
unlisted links always worked — the copy-link toast just checked for
visibility === "public" instead of !== "private", flagging unlisted
recipes as broken when they weren't.
