Kotlin has no part-of like Dart, so this extracts three cohesive
method groups into standalone internal helper classes held as
private delegates: DevicePolicyVpnDns (VPN/Private DNS pinning),
DevicePolicyLocation (location permissions), DevicePolicyUninstallGuard
(uninstall blocking). DevicePolicyBridge's public API is unchanged --
every method MainActivity.kt/EnforcementService.kt call directly
still exists as a one-line delegating wrapper.
Verified with gradlew compileDebugKotlin + test --rerun-tasks
(BUILD SUCCESSFUL, 40 tests / 0 failures).
