Use activity endpoint in Counts window to get more meaningful deployment information for batches

[DeamonDev]

💥 Proposal

Currently we use endpoint: /processes/:processName/deployments in order to fetch all deployments and based on that we are able to provide counts for previous deployments. For batch-type scenario there are additional actions which may be performed: run now action and deployment performed by scheduled execution. Using endpoint: /processes/:scenarioName/activity/activities recently added in #7036 we are able to fulfill these information.
