This includes:
1. Fix Race Condition: The call to `logRequest` is moved before
`trackUidAndRegisterNetworkRequest`. This prevents a race condition
where the `NetworkRequest` object could be modified on the handler
thread before its initial state was logged.
2. Clear Metrics on Pull: The metrics map is now cleared after the
data is pulled. This changes the atom from a cumulative
counter to a periodic one, simplifying server-side aggregation.
