This replaces #768. CI there failed the check of recorded content API answers: the new tests had been recorded against the Release 98 graph, while the suite's recordings are from Release 97. They now replay the Release 97 answers already recorded for the same requests. Moving the whole suite to Release 98 is its own change.

With an analysis token, the render page reported ready as soon as a view was drawn. That was before its analysis colouring arrived, and, for a result holding one resource besides TOTAL, before the second load that colours it for that resource, as the pathway browser shows it. The render service then cached the figure under the token, uncoloured or coloured for TOTAL. A token whose result could not be read was dropped, and the figure was drawn with no colouring at all and reported ready.

What changes

• AnalysisService.settled: the result on show is the one the address settles on, including the default resource's second load.
• Each view says what it shows:
  • the diagram and the illustration say which analysis they last coloured;
  • the overview says whether its tree is the one fetched for the current token and resource.
• The render page:
  • waits on these before it is ready;
  • publishes what it coloured in __renderState.analysis (token and resource);
  • reports an error when the analysis cannot be read.
• Render cache key v12, so figures cached without their colouring are not served. The README's readiness notes say why.

Tests
Four new e2e tests on the render page, with a made-up token answered in the test:

• the diagram, the illustration and the genome-wide view, each with the loads for the result's resource held back three seconds;
• a token whose result is gone (410).

All four fail on the previous page code: it was ready before the held-back colouring arrived, and the 410 case gave a figure rather than an error. All four pass with this change.

Belongs to pdf-export's spec 002 (the analysis report), whose plan makes this its step 0. It also fixes figures rendered with a token today.
