Security (R6.2): Haertung nach Audit

- Security-Header-Middleware (nosniff, X-Frame-Options, Referrer-/
  Permissions-Policy) global, proxy-unabhaengig; CSP bewusst separat.
- Firmenlogo-Upload im Create-Formular durch den ImageService-Pfad
  ersetzt (Mime-Whitelist ohne SVG, Re-Encode, UUID-Name) - vorher
  rohe store()-Ablage ohne Server-Validierung (SVG/XSS moeglich).
- Rate-Limits ergaenzt: Passwort-Reset (3/E-Mail + 15/IP pro Std.),
  Registrierung (10/IP pro Std.), throttle auf magic-login- und
  pm-vorschau-Consume-Routen (Defense-in-Depth).
- EnsureUserIsCustomer als persistente Livewire-Middleware
  (symmetrisch zum Admin-Gate, greift auch bei Folge-Requests).
