Manual test cases — Publish dialog migration and title crash fix

Setup: log in on an archive with at least one private folder (with items), one private record, and one already-published item.
EXPECTED: only the Publish dialog is affected by this PR — opening it, its title, and the folder publish flow.

---

Dialog title — private items

1. Open Publish on a private folder and keep the browser console open.
   • EXPECTED: The title reads "Publish " and no TypeErrors appear in the console. (Bug fix — the template read folder_linkType unguarded, which folders loaded through the Stela API don't have, causing a repeating TypeError on every change detection cycle.)
2. Open Publish on a private record.
   • EXPECTED: The title reads "Publish " with no console errors.

Dialog title — already-public item

1. Open Publish on an item that is already public.
   • EXPECTED: The title reads "Get public link for " and the public link is shown immediately.
2. Click "Copy link".
   • EXPECTED: The link is copied and the button changes to "Link copied".

Publishing a folder

1. Open Publish on a private folder with items and click Publish.
   • EXPECTED: The spinner resolves and a public link appears (the dialog polls the Public workspace through the new endpoint to find the copy).
2. Follow the generated link.
   • EXPECTED: The public copy opens. (Known open issue: the copy may appear empty — under investigation with the backend team; if it reproduces, capture the v2/folder/{id}/children response.)

Publishing a record

1. Open Publish on a private record and click Publish.
   • EXPECTED: A public link appears; following it opens the record in the public view.
