fix(assets): drop Vite preload hints (silence 'preloaded but not used')

With one CSS + one JS entry the <link rel=preload> sits next to the matching
stylesheet/script and adds no value, but it triggers Chrome's 'preloaded but
not used' console warning (amplified by DevTools 'Disable cache', which
double-fetches the CSS). Disable preload tag generation; stylesheet and script
still load normally.

+- **Konsolen-Warnung „resource was preloaded but not used".** Vite legte zu jeder Seite einen
+  `<link rel="preload">` für CSS/JS zusätzlich zum normalen Stylesheet/Script an. Bei nur einem
+  CSS- und einem JS-Bundle bringt der Preload nichts (die Tags stehen ohnehin direkt daneben), löste
+  aber Chromes „preloaded but not used"-Warnung aus — verstärkt durch DevTools „Cache deaktivieren",
+  das die CSS doppelt lädt. Die Preload-Hints werden jetzt weggelassen (`Vite::usePreloadTagAttributes(false)`);
+  Stylesheet und Script laden unverändert.
