HealthBank Hormone Corrector - for MtF

This script corrects the display of hormone test results (such as androgens and estrogens) in the HealthBank app to use female standards for color coding, regardless of the gender on the ID. This ensures that transgender women who have not updated their ID gender see accurate and fair representation of their hormone levels.
