commit 48498fbd26536fd330d53a0621587ade92a041fe

settings: Display policy indicator when PIN is disabled by policy.

Previously would just hide the Screen options section. Now the policy indicator gets shown next to the Screen options header, and the options get disabled. If PIN is also disabled some other way (feature, supervised user), the Screen options section remains hidden.

Test: manual
