[PER-10680] Migrate from navigateLean to getWithChildren for refresh current folder

[aasandei-vsp]

Manual test cases — current folder refresh moved from navigateLean to getWithChildren, sort preview in the browser

Setup: Sign in as the owner of an archive with a folder that mixes records and
sub-folders. You also need a second account with a folder
shared to it as Viewer.

Sort preview ⭐

(run in both the multi-column list header and the single-column Sorted by … menu
on a narrow window — same code path, two entry points)

Scenario — name

1. Open the mixed folder in list view and click the Name header.
   • EXPECTED: Rows reorder A–Z with folders and records interleaved by name.
2. Click Name again.
   • EXPECTED: Rows reorder Z–A.

Scenario — date

1. Click the Date header.
   • EXPECTED: Oldest first.
2. Click Date again.
   • EXPECTED: Newest first.

Scenario — type

1. Click the Type header.
   • EXPECTED: Folders group first, then records grouped by type; within a group the
     rows are A–Z by name.

Scenario — save and reload

1. With a preview active, click Save next to the header.
   • EXPECTED: The Save control disappears.
2. Reload the page.
   • EXPECTED: The list comes back in the sort you saved.
3. Compare the reloaded order with the previewed one.
   • EXPECTED: They should be identical.

Scenario — viewer can preview but not save

1. Sign in as the Viewer account, open the shared folder and click Name.
   • EXPECTED: The list reorders. No Save control is offered.

Refresh after a change ⭐

(this is critical change of this PR — every path that calls the refresh)

Scenario — new folder

1. In a folder you own, click the "Create folder" button and give it a name.
   • EXPECTED: Toast Folder <name> has been created. The new row appears in its
     sorted position.

Scenario — upload

1. Upload an image into the folder and wait for the upload progress to finish.
   • EXPECTED: The new row appears without a reload.
2. Watch the new row for a few seconds.
   • EXPECTED: Its thumbnail fills in on its own, as before.
3. Upload three files at once.
   • EXPECTED: All three appear.

Scenario — delete

1. Select two rows, one folder and one record, and delete them.
   • EXPECTED: Both rows disappear and the selection is cleared.

Scenario — move and copy --------CHECK ON DEV

1. Select a folder/record and select move. From the folder picker, choose a sibling folder to move it to.
   • EXPECTED: Toast ending in moved successfully; the row leaves the list after
     the short delay.
2. Do the same with Copy on a folder.
   • EXPECTED: Toast ending in copied successfully.

---

A change while a preview is active ⭐

1. Click Name twice so the list is Z–A, and do not save.
2. Create a folder named Aachen.
   • EXPECTED: The list stays Z–A and Aachen appears at the bottom. The header
     still shows the descending indicator and Save is still offered.
3. Upload a file named Zzz.jpg.
   • EXPECTED: It appears at the top; the order is still Z–A.
4. Click Save, then reload.
   • EXPECTED: The reloaded list is Z–A.

---

Error handling

Scenario — create fails or the refresh after it fails

1. Open the New folder prompt, set devtools network to Offline, then confirm with
   the name Offline test.
   • EXPECTED: An error toast appears and the prompt closes.
2. Set the network back to Online and reload.
   • EXPECTED: The app is usable and a new New folder works normally, whether or
     not Offline test was created before the connection dropped.

---

Regression — untouched paths

Cheap sanity checks; these code paths were traced as unchanged by this PR.

1. Navigate into a folder and back.
   • EXPECTED: Works correctly.
2. Open an unlisted share link to a folder.
   • EXPECTED: The unlisted shared folder loads correctly.
