fix(access): dev unlock defaults OFF

Browse source 
ACCESS_DEV_UNLOCK was opt-out (anything but 'false' enabled it) and
access.example.json shipped it on, so a gated production machine would
render a visible gate-bypass button on the lock screen by default. Flip
to opt-in (=== 'true'), update the example file and the provisioning
schema comment to match.
