Use exflcalproxy by default for CalCat access
Description
At present, anyone running one of the notebooks we've converted to the new CalCat API needs to configure an Oauth client ID & secret in a config file in their home folder. With this change, these notebooks will use the internal exflcalproxy instead, requiring no configuration.
In production, we'll still use Oauth directly, so it's easy to track which requests come from the calibration system, and so we're not dependent on the proxy. I've ensured that xcal and xcaltst have the URLs explicitly configured and the use_oauth2: true option set.
I also reordered the URLs to make the structure clearer - the token, auth & refresh URLs are all part of Oauth, so they're ignored if use_oauth2 is false.
How Has This Been Tested?
