Currently, frontend loads device images from third-party domain https://www.zigbee2mqtt.io/, leaking potentially sensitive information, as the address might be externally routable IPv6 address, etc. We need to remove crossorigin="anonymous" to stop sending Origin header, and add referer="no-referer" referrer policy to stop sending Origin header. Note that as <image> elements don't support refererpolicy attribute, we have to add document-wide policy. Which is a good idea, as it also prevents leaks when following links.
