Summary: Fixes T5492. I figured this would be easier to just fix than write a guide for; it actually took me an hour, but I spent like 75% of that futzing with my editor. - The Move controller currently accepts either a slug or an ID. I can't find any callsites which pass a slug, and this doesn't make sense. Pretty sure this was copy/pasted from Edit or something. Only accept IDs. - Slightly modernize the Move controller (newDialog(), handleRequest(), $viewer). - When the user enters a bad slug, warn them that we're going to fix it for them and let them accept or reject the changes. - Don't prefill the edit note (this feels inconsistent/unusual). - On the form, label the input "Path" instead of "URI". - Show the old path, to help remind the user what the input should look like. - When a user tries to do a no-op move, show a more tailored message. - When the user tries to do an overwriting move, explain how they can fix it. - When normalizing a slug like `/question/???/mark/`, make it normalize to `/question/_/mark`. Test Plan: - Tried to move a document to itself. - Tried to overwrite a document. - Did a bad-path move, accepted corrected path. - Did a good-path move. - Did a path move with a weird component like `/???/`. - Added and executed unit tests.
