- Replace broken icon-only sidebar collapse with off-canvas hamburger menu
that slides in from left (hidden by default on <768px)
- Add sidebar overlay backdrop, auto-close on nav/logout
- Rename 'Cantaloupe Sync' to 'Import' in sidebar and 'Excel Import' in page
- Remove 'Sync Now' button and backend subprocess auto-export entirely
- Keep manual Excel file upload as the only import path
- Update empty-state text and upload handler to work without Sync Now btn
- Changed subprocess from 'python' to 'sys.executable' (fixes FileNotFoundError
in systemd — venv python not in system PATH)
- Added '📤 Upload Excel' button to admin frontend sync page
- uploadSyncFile() sends file to the same /api/admin/cantaloupe/sync endpoint
(which already supported file upload — frontend just didn't expose it)
- Users can now use 'Sync Now' for auto-download or 'Upload Excel' for manual
