test(260924-m4n): flackernden Marktplatz-Test entschaerfen, act-Warnungen der Proxmox-Kachel weg

- tenant-selector: Komponenten statisch statt im Test dynamisch importiert
  (Laden zaehlte in die 5-s-Frist des ersten Tests), SUPER_ADMIN/ADMIN in
  zwei it aufgetrennt
- marketplace/marketplace-filters: gleiche Umstellung; userEvent an die
  falsche Uhr gekoppelt statt auf shouldAdvanceTime zu warten
- proxmox-widget: Rendern wartet das erste Laden in act() ab (81 Warnungen weg)
- Todo 2026-09-23 nach completed/
