1-click button to download logs

The current command in the dashboard to download logs requires copy-pasting into a terminal with `gcloud` installed.

We should instead be able to hit the `entries.list` HTTP endpoint: https://cloud.google.com/logging/docs/reference/v2/rest/v2/entries/list

This should give the same result as `gcloud logging read`: https://cloud.google.com/logging/docs/reference/tools/gcloud-logging#listing-logs

With that, we should be able to download the logs from the dashboard UI
