Mass report update - FLOPS

[jkirk5]

Summary

Updates mass reporting for FLOPS-based mass to conform to SAWE RP-8 standard.
Some mass variables have been renamed to comply with the standard, and the FLOPS-based mass summation component was reworked to group masses appropriately.

Generative AI was used to write a new test that checks matching between hierarchy variable names and string representation (test_var_structure.py). The Cursor IDE was used, which does not expose which specific models it uses. Manual review and minor tweaks were done by hand.

Surprised the variable match test didn't find more mistakes in the names. Guess they are all good now.

Note: there is a test regression that should be investigated.
