Z-score Normalization!!!

[daniel-panhead]

shoutout to @jkuo630 @ErpingS

Description

• Added new temp button for triggering normalization on all graded applications
• Resulting calculated z-scores are put back in firebase for each applicant as normalizedScore in the same location as score

Other considerations

• Relies on the new application status updates - (ex. the in progress tag) for accurate results
• Everything's client side because it probably won't actually take that long to run
• We didn't test
