anfra serve gets anfra Cloud's look
`anfra serve` now has anfra Cloud's sidebar, header, fonts and colors, and its command palette finds your apps as well as commands.
anfra serve and anfra Cloud now share one design: the same fonts, type, colors, icons and components, and the anfra logomark in the sidebar. A Data App looks the same while you build it and once it's published.
The command palette (⌘K or Ctrl+K) searches your apps as well as commands, so you can open another app from the keyboard. The Inspect panel and the menus and modals that plugins draw take the same theme, in light and dark.
