Do not merge before #996

Manual test cases — Replace navigateLean with getWithChildren

Setup: log in on an archive with nested folders, records, a shared folder, and a folder set to Timeline view.
EXPECTED: all folder navigation now goes through the Stela v2 endpoints — the flows below cover every migrated consumer.

---

Private navigation

1. Log in and open My Files.
   • EXPECTED: The folder contents load with correct names and thumbnails.
2. Copy the URL of a nested folder and open it in a new tab.
   • EXPECTED: The folder loads directly from the URL (this path resolves the folder id through the legacy endpoint first).
3. Navigate several levels deep, then go back up using the breadcrumbs.
   • EXPECTED: Breadcrumb labels are correct and each link navigates to the right folder.
4. Edit the URL to a nonexistent folderLinkId.
   • EXPECTED: An error toast appears and you are redirected to My Files — no blank page.

Apps folder

1. Navigate to /apps.
   • EXPECTED: The Apps folder contents load correctly.

Share preview

1. Open a share link to a shared folder.
   • EXPECTED: The shared folder contents load.
2. Open a share link to a single record.
   • EXPECTED: The record preview renders with the Shares > Record breadcrumb.

Public archive

1. Visit your public archive (/p/archive/...) and browse into folders.
   • EXPECTED: Contents load; opening a record works.

Timeline view

1. Open a folder set to Timeline view and click a folder inside the timeline.
   • EXPECTED: The clicked folder's contents load in the timeline without errors.

Folder content refresh

1. Upload a file into a folder.
   • EXPECTED: The listing refreshes and shows the new file without a manual reload.
2. Rename, move, and delete an item.
   • EXPECTED: The folder refreshes correctly after each operation.
3. Change the sort order.
   • EXPECTED: The list re-sorts and the order persists after navigating away and back.

Publish dialog

1. Open Publish on a private folder.
   • EXPECTED: The title reads "Publish " and there are no TypeErrors in the console. (Bug fix in this PR — the template read folder_linkType unguarded, which Stela folders don't have.)
2. Open Publish on an already-public item.
   • EXPECTED: The title reads "Get public link for " and the link is shown.
3. Publish a record and follow its link.
   • EXPECTED: The record opens in the public view.
4. Publish a folder and follow its link.
   • EXPECTED: The public copy opens and shows its contents. (Known open issue: the copy may appear empty — under investigation with the backend team; capture the v2/folder/{id}/children response if it reproduces.)
