Add favicon upload to the site editor

Browse Source 
Data.favicon names a blob in the content-addressed files store (no
migration: msgspec default). PUT/DELETE /_api/settings/favicon upload and
clear it; when set, every page links it as <link rel="icon">, otherwise
browsers fall back to the build's /favicon.ico. SiteEditor shows a preview
with upload/replace/remove and applies the change to the live page head.
