Stats for clicks lags behind stats for views

### Impacted plugin

Jetpack

### Quick summary

In the early hours of the day, it seems like the views go up while the uniques lag behind and catch up hours later.

However this doesn't seem to be Mobile specific:

### Steps to reproduce

1. On a site with traffic
2. Check the stats in the early hours. Views go up faster than uniques
3. Check later - the numbers catch up

### Site owner impact

Fewer than 20% of the total website/platform users

### Severity

Moderate

The issue names no file, test, or entry point; begin by tracing Jetpack’s views and uniques statistics paths and compare their early-day update timing with the linked WordPress-iOS report. Reproduce the discrepancy on a traffic-bearing site and treat the work as complete when the cause of the lag is identified and the metrics follow the intended timing.
