Get a time series of form performance statistics within a date range. The response returns one row per
time bucket, each carrying the same counters as the summary report: views (form displayed),
interactions (visitor engaged with the form), submits (form successfully submitted), and signups
(contacts gained). Use GET /forms/{formID}/report instead when only totals and a per-device breakdown are
needed; this endpoint does not return a device breakdown.

Granularity: when granularity is omitted it is derived from the length of the requested range —
hour for a single day, day for up to a month, month for up to two years, and year beyond that.
When it is provided it must be available for the range, otherwise the request is rejected with 400:
hour requires a single-day range, day a range of up to a month, week a range of up to three months,
month a range longer than a month and up to two years, and year a range longer than two years.

The period value of each row is formatted according to the granularity in effect, and buckets are
aligned to the brand's timezone.
