* Replace Dev jpgraph/jpgraph with mitoteam/jpgraph
PR #2979 added support for mitoteam/jpgraph as an alternative to jpgraph/jpgraph. The package jpgraph/jpgraph is abandoned in composer, and the version loaded with composer has been unusable for some time. This PR removes the dev requirement for jpgraph/jpgraph, and adds a dev requirement for mitoteam/jpgraph in its place.
With a usable graph library, a number of tests and samples that had been disabled are now re-enabled. A lot of new functionality has been added to Charts recently. Some of that new code has exposed bugs in JpgraphRendererBase. I have fixed those where I could. A handful of exceptions remain; I will investigate, and hopefully fix, those over time, but I don't feel it is necessary to fix them all before installing this PR - we are already way ahead of the game with the graphs that are working.
Three members had been ignoring code coverage in whole or in part because of the unavailability of a usable graph libray. Code coverage is restored in them. I am relieved to report that, although they aren't completely covered, adding them did not reduce code coverage by much - it is still over 90.4%.
I took a look at JpgraphRendererBase and Phpstan. Phpstan reports 128 problems. When I added some docblocks to correct some of those, the number increased to 284. Sigh. I will investigate over time, but, for now, we will still suppress Phpstan for JpgraphRendererBase.
I do not find a License file for mitoteam. However, there also wasn't one for jpgraph in the first place. Based on that and the discussion in #2996 (mitoteam will be used in exactly the same manner as mpdf), I don't think this is a problem. IANAL.
* PHP 8.2 Problems
Tons of "cannot create dynamic property" deprecations in jpgraph. Disable the test with most of those for now; leave the two with only a handful of messages enabled.
* Correct Failures in 2 Stock Charts
Down to 6 templates on which Render fails.
* jpgraph seems to be finally dying with PHP. Until we have a valid alternative, disabling this run for PHP because it errors
https://github.com/HuasoFoundries/jpgraph looks like a natural successor, but it isn't BC so it will require some work to integrate
