Currently on first load of a measurement page a raw_measurement request is triggered. As we have seen in the logs this is a quite expensive call and it has been leading to OOMs.

Since the release of OONI Probe 6.0.0, given that we don't have in-app support for viewing measurements, these requests are more than they used to be.

This task is about replacing the raw measurement calls to happen only when a raw measurement is requested and make use of the observations endpoints instead to retrieve the relevant data to display in the measurement pages.
