Monthly active users: app starts and distinct users who started the app, per calendar month, over the rolling 12 months ending today.

• Always monthly: takes no date_range, periodicity or filter.
• For one application, returns {data: {app_starts: [{period: "YYYY-MM", value}], unique_users: [{period, value}]}}.
• Without application_id, returns {data: {applications: [{mobile_application_id, mobile_application_name, client_name, chart_data: {app_starts, unique_users}}]}}, with one entry per application you can access. Values are never summed across applications.
• Unit: count of app starts, or of unique users, per month.
• unique_users is a per-month distinct count: do not sum it across months.
