fix: Update placeholder catalog with Phase 0b placeholders

Added ~40 Phase 0b placeholders to get_placeholder_catalog():
- Scores (6 new): goal_progress_score, body/nutrition/activity/recovery/data_quality
- Focus Areas (8 new): top focus area, category progress/weights
- Body Metrics (7 new): weight trends, FM/LBM changes, waist, recomposition
- Nutrition (4 new): energy balance, protein g/kg, adequacy, consistency
- Activity (6 new): minutes/week, quality, ability balance, compliance
- Recovery (4 new): sleep duration/debt/regularity/quality
- Vitals (3 new): HRV/RHR vs baseline, VO2max trend

Fixes: Placeholders now visible in Admin UI placeholder list
