### What happened?

Title:
Settings page is slow while loading folder status and blocks folder actions

Description:
The Settings → Folders page becomes noticeably slow when folder status is being fetched.
While the folder status is loading, the UI becomes partially unresponsive and actions like
folder deletion or uploading another folder do not work reliably.

This makes basic folder management difficult and affects overall usability of the Settings page.

Environment:
- OS: Windows
- Browser: Chrome
- PictoPy: current main branch

Pre-conditions:
- At least one folder already exists
- Folder contains multiple files

How to Reproduce (Step-by-step):
1. Open PictoPy in the browser
2. Navigate to Settings → Folders
3. Click on any existing folder
4. Observe that the folder status takes several seconds to load
5. While the folder status is still loading:
- Try deleting the same folder, OR
- Try uploading another folder
6. Notice that the UI becomes slow and the action either gets stuck or does not complete

Video Demo:

Actual Behavior:
- Folder status loading is slow
- UI becomes unresponsive during loading
- Folder delete does not work immediately
- Uploading another folder often gets stuck

Expected Behavior:
- Folder status should load quickly
- UI should remain responsive
- Folder deletion and uploads should work independently of status loading

Additional Context:
This issue was discussed during the recent PictoPy Google Meet and is being raised with
a video demo and detailed reproduction steps as suggested.
