Use citadel-trunk use case for mobile if on proper schedule types

Summary: "schedule_type" here is not necessary from job.. there's [more complex logic](https://fburl.com/code/7w0ri28k) to determine which "schedule type" to trigger job with.. I think we should be good to use "citadel-trunk" for all those trunk schedule types.
