Subject: [PATCH] Fix Cantaloupe Sync: use sys.executable + add Excel file
 upload button
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- 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
