fix(schedule): serialize ScheduleState into gRPC CreateScheduleRequest proto

RequestMapper.createScheduleRequest was missing the state field, causing
initialState to be silently dropped on the gRPC path. Add TypeMapper
overloads for the thrift→proto direction (schedulePauseInfo and scheduleState)
and wire state into the proto builder. Add a RequestMapper-level test that
verifies state and pauseInfo survive the full thrift→proto conversion.
