docs(web): reflect Explorer AUMID pin + Atera-under-SYSTEM

- spec: Atera row now SYSTEM + /qn + no MFA; taskbar row notes Explorer is
  pinned via AUMID to avoid the duplicate-instance / unpinnable bug.
- descriptions.json: update 02 Atera item and 04 taskbar item accordingly.
- navod: drop the obsolete "confirm Atera MFA" warning - it installs silently
  under SYSTEM now.
