- Add biological_sex field to User model, profile API, and ProfilePage toggle (male/female) — used to select the correct ACSM VO2 max threshold table
- Replace simple VO2 max number in daily snapshot with a colour-coded SVG radial gauge (Very Poor=red, Poor=orange, Fair=green, Good=blue, Excellent=purple) driven by sex- and age-appropriate thresholds
- Shrink Sleep widget to half-width, expand Heart & HRV to half-width; reorganise Heart & HRV internals into a 2×2 grid to reduce vertical height
- Add connectNulls + showDots to VO2 Max trend chart so sparse readings connect with a continuous line
- Add 3Y and 5Y range options to the Trends selector; increase allDays limit to 2000 for full 5yr snapshot navigation
