dsh-loopback-bridge: Make the DSH Web Settings Page Writable on Local and Public Networks

The `dsh-loopback-bridge` plugin injects logic that tricks the browser, resolving the issue that the DSH web settings page supports localhost access only by default and enabling remote configuration over a LAN or public network. The plugin can be installed independently without affecting the official package, and it takes effect immediately after installation. Installation requires the `--trusted-host` parameter, and version compatibility should also be considered. When used in a public network environment, it must be paired with an authentication layer to ensure security.
