Always get at least an A on post-song evaluation page

[4rcadian07]

Describe the bug No matter what grade I get below an A, the evaluation page appearing right after the song is over shows an A. The correct grade is displayed afterwards at the song selection wheel. (Note - this is a similar but different bug from #30, as it seems to replicate in any fail mode and with any grade)

To Reproduce Steps to reproduce the behavior:

1. Fresh install of Outfox 4.19 (no need to change any options)
2. Install XX--STARLiGHT 3.0 beta 1
3. Create a named profile
4. Play any song (works with the Outfox credits song) and get enough misses for a low grade (e.g. C or D) (tried reinstalling and on two different Win 11 computers and always get this behavior)

Desktop (please complete the following information):

• OS: Win 11
• Outfox 4.19 (also experienced with ITGMania v. 0.7.0)
• Theme Version: v3.0 Beta1

Additional context I'll try to see if I can replicate the bug with theme version v2.x

Example screenshots - song incorrectly rated as A+ on song eval, and correctly showing C+ on high scores afterwards.

Update: this specific behavior can be fixed by updating OutFox\Save\ThemePrefs.ini, ConvertScoresAndGrades=true (or changing the corresponding setting in settings). So I guess the bug is that if ConvertScoresAndGrades=false, the recorded song grade doesn't match the post-song eval (and whatever the "non-converted" eval is, it is set super lenient to always give at least an A).

There is a separate inconsistency which is that even with ConvertScoresAndGrades=true, the high scores for each song still display the other grading system. @Inorizushi, could you point me to which lua file I could change that behavior in?
