Replace ECM AppOps call with service
A new ECM service was introcuded in changeId
I831391e4437b51b3312b5273a2360bd029a3d8ee.
We begin calling it, and update/cleanup method signatures to match.
Note: There are two feature flags:
1. enhancedConfirmationModeApisEnabled - read only, protects the
mainline API.
2. extendEcmToAllSettings - runtime - gates calls to the above APIs.
We use both so we can ramp up in teamfood as needed.
