With authentication off every caller that reaches the port is the same
local owner, and the checks that tell a person from a script are
headers the caller chooses. Any process or agent that could reach the
port could grant host operations, set deny rules and turn the blanket
approval on.
UI host grants are now locked by default in that mode. The policy file
and flags still grant, and every write route answers 403
locked_by_deployment with a sentence that says why. The overview and the
preview carry the lock and its reason for the page. The new flag
--addon-host-ui-grants-without-auth turns the UI grants on knowingly and
logs a startup warning. With sign-in on nothing changes.
