test(apiform): cover comma-form float32 regression

[saioai]

The float32 formatter from #78 merged through #119, but the direct []float32{0.1, 1.5} regression from #78 was left behind. Add the scalar control and comma-array case contributed by @sylvesterkaczmarek so the original behavior in #77 is covered.

Before #119, the array case failed with 0.10000000149011612,1.5. On current main, it passes with 0.1,1.5. Ten race-enabled TestEncode runs, the apiform package tests, and git diff --check passed.

Fixes #77.
