rebaseline_server: use new intermediate JSON format

This is another big part of this CL: use of defined constants for keys in the
intermediate JSON.

Previously, both the client-side code (HTML+Javascript) and server-side code
(Python) used string literals, without any mechanism in place to keep them in
sync.  If we had changed some of those literals, it could have easily broken
other code.

I'm sure we can still break things now, but it should be harder to do.
