home-assistant: Use subdomain for Zigbee/Z-wave UI

Having the Z-Wave and Zigbee admin interfaces exposed as sub-paths under
*homeassistant.pyrocufflink.blue* made it difficult to use Authelia.
Since I have a Firefox container tab specifically for Home Assistant,
the login redirect would open a new tab in a different container, since
Authelia is hosted at *auth.pyrocufflink.blue*.  In order to log in, I
would have to temporarily disable "designated sites only" for the Home
Assistant tab container.  Using subdomains for the admin interfaces
avoids this issue, since I can use a different container for them, one
that does not have the "designated sites only" setting, since I am less
worried about accidentally leaking data to sites on the Internet from
them.
