feat: VM-Liste pro Projekt (Desktop-Panel) — Start/Stop/Verbinden

- Brain: project_vms.py (Registry /shared/config/project_vms.json pro Projekt) +
  Endpoints GET/POST/DELETE /projects/<id>/vms + boot/stop (via SSH aria-wohnung
  aria-vm auf dem Host; Status aus `aria-vm list`).
- ARIA-Tools vm_register/vm_list (aufs Request-Projekt) + Seed-Regel: nach dem
  VM-Bau registrieren, damit sie in Stefans Desktop-Panel auftaucht.
- App: brainApi VM-Methoden + ProjectVm-Typ. Neues DesktopTile — pro Projekt die
  VM-Liste (leer bis registriert), Start/Stop/Verbinden; Verbinden oeffnet noVNC
  (VncTile mit dem VNC-Port der VM). Deck rendert DesktopTile statt VncTile.

py/tsc clean.
