Telemetry-disable settings now apply before verification completes and fail closed.

The disableEssentialTelemetry and disableNonessentialTelemetry managed settings now carry remotePolicy.applyUnverified: true and failClosedValue: true, so they are honored even before signature verification completes and default to the blocking (true) value if verification fails.
