Remove the ForceCacheControl wrapper from the ready ServeHTTP path so proxied responses keep upstream Cache-Control and Expires. Centralize strong no-store headers via setNoStoreHeaders for the loading page, static CSS/JS, favicon, and SSE wake events. Add tests covering loading responses and upstream header preservation.
