Non-admin users were seeing all users' root folders, including the
admin's. Three root causes fixed:
1. Backend: list_root_folders now extracts AuthUser and filters
results so each user only sees their own home folder at the
root level (folders matching 'My Folder - {username}' or
'Mi Carpeta - {username}').
2. Frontend: findUserHomeFolder() searched only for the Spanish
pattern 'Mi Carpeta - {username}' but the backend creates
folders with the English pattern 'My Folder - {username}'.
Now checks both naming conventions.
3. Frontend: when the home folder was not found, the code fell
back to folderList[0] — which was usually the admin's folder.
Removed that dangerous fallback; now shows empty root instead.
