perf(frontend): split chat streaming, load Inter, isolate admin CSS

Settled messages no longer rebuild on every token, Inter is actually requested, and admin routes drop the 33 KB chat stylesheet. Root force-dynamic is gone so public shells can prerender without changing the no-store Cache-Control contract. Co-authored-by: Cursor <cursoragent@cursor.com>
