Simone cd2dc9cb6a fix(web): refuse unauthenticated bind on non-loopback address (W5)
In open mode ([web.oidc] unset) the dashboard has no login. Binding a LAN/any address there would expose host-management unauthenticated, so ci web serve now aborts unless the bind host is loopback. Auth-configured deployments bind LAN as before.

"""Tests for ``ci web serve`` (W4 of the web-UI plan).
Two concerns:
1. Behaviour: ``ci web serve --help`` works and ``serve`` builds the app and
calls ``uvicorn.run`` with the right host/port (``uvicorn.run`` is
monkeypatched -- no real server is ever started). ``CI_ROOT``/``CI_CONFIG``
are pointed at an empty tmp dir so the test never depends on this host's
real ``/var/lib/ci/config.toml``.
2. Architecture: ``commands/web.py`` must import only ``click``/stdlib at
module scope. ``fastapi``/``uvicorn``/``ci_orchestrator.web`` may only be
imported lazily, inside the ``serve`` function body -- this keeps
``ci --help`` working when the optional ``[web]`` extra is not installed.
