Assets feature not working in a new graph, but working fine in a Demo graph

### What Happened?

Since I'm a new Logseq user, I learned and tested all the features in a Demo graph, then created a new personal one.
In that new graph, the Assets feature does not work at all:
- uploading directly in # Assets page
- drag&drop into a node
- / upload a file

No file appears after all of these actions.

- But when I switch to a Demo graph, everything works fine.
- In the folder of my graph on Mac, there are many files I've tried to upload, many of them are just duplicates from all the tries, but not showing in the Assets page.
- Then I've tried to export a SQL backup file, deleted a graph from graphs list, imported it again - didn't work.
- All of the screenshots I've attached are after importing a backup SQL, so there are no duplicated files I've mentioned previously.
- I also gave Logseq full disk drive permissions on my Mac

### Reproduce the Bug

Idk, create a new graph and try to upload assets :)

### Are you willing to submit a PR? If you know how to fix the bug.

Start by reproducing the asset uploads in a newly created graph and compare the result with a Demo graph, using the attached db-worker-node-20260831.log for errors. The fix is complete when direct upload, drag-and-drop, and / upload make files appear in the Assets page for the new graph.
