Nuxt3=>4, spa-loader, css shenanigans...:

...css shenanigans: daisyui may have had a breaking change at 5.3.0, it wrecks the ui here, as tailwind forces its own styles over daisyuis overrides, for now staying at ~5.2.5, for good measure also @nuxtjs/tailwindcss stays at ^6.13.2 (6.13.2 in pnpmlock) - this may be, because (but i'm not sure) @nuxtjs/tailwind is tailwind3 and not tailwind4?

Nuxt3=>4 migration:
also changed nuxtimage settings, as the docs have been fixed, path changes, etc
