Serve a local web UI from bangerd

Browse source 
Add a localhost-only web console so VM and image management no longer depends on the CLI for every inspection and lifecycle action.

Wire bangerd up to a configurable web listener, expose dashboard and async image-build state through the daemon, and serve CSRF-protected HTML pages with host-path picking, VM/image detail views, logs, ports, and progress polling for long-running operations.

Keep the browser path aligned with the existing sudo and host-owned artifact model: surface sudo readiness, print the web URL in daemon status, and document the new workflow. Polish the UI with resource usage cards, clearer clickable affordances, cancel paths, confirmation prompts, image-name links, and HTTP port links.
