Add log warning when set rendering cannot fit mods

[robojumper]

It always bothered me that we didn't have an easy way to test for consistency between the LO worker and fitMostMods, so this adds a log warning if we fail to assign some mods that LO thought were possible to fully assign. This needed a fix very similar to #8616 to not throw random warnings when changing the armor energy settings.

Maybe we'll get some more false positives that need fixing but I do think this additional error checking is nice to have when hacking on LO.
