feat(icons): Bundle icons locally to drop the Iconify API

Enable @nuxt/ui's client-side icon bundling (nuxt/ui#6635) so every
icon — Nuxt UI's own component icons and the app's fa6/lucide icons —
is embedded into the build instead of fetched from api.iconify.design
at runtime. This restores offline icon rendering and removes the
third-party runtime dependency. Verified against a production build:
the icon SVG data is inlined and the running app makes zero requests
to api.iconify.design.

@nuxt/ui is temporarily pinned to the ephemeral pkg.pr.new preview of
#6635, which is merged but not yet in a published release. Swap it
back to a normal semver once the next @nuxt/ui release ships; the
vite.config and @iconify-json/lucide changes stay identical.
