fix(build): disable @nuxt/fonts external providers

Build was failing on Dokploy when fonts.bunny.net was unreachable from the
build container. Fonts are already loaded at runtime via the explicit
<link rel="stylesheet"> in app.head, so the auto-resolver is redundant —
disable all external providers to remove the build-time network dependency.
