Baseline profile used by the historical PDMeasure analysis

The old PHP site stored a compact profile with gender, diagnosis, month/year of birth, diagnosis date, and first-problem date. This rebuild restores that structure cleanly.

Why the form looks like this

The historical CSV headers were `gender`, `dx`, `dxother`, `yob`, `mob`, `yDX`, `mDX`, `yFP`, and `mFP`. This page is organized around those exact data points so that local exports stay compatible with the old analysis logic.
