I see that fonts/icons are loaded from remote servers (e.g., api.iconify.design) which poses security and performance risks. I'm planning to bundle these assets locally (e.g., in a public/assets folder) and update the code accordingly. Please let me know if my understanding is off or if there are any additional considerations.

We already cache the icons:

headlamp/frontend/src/components/App/icons.ts

Line 17 in 5e101d6

const mdiIcons = {

Maybe some of them are not cached and we should fix it.
