fix: Phase 0b - body_progress_score + placeholder formatting

Fixed remaining placeholder calculation issues:

1. body_progress_score returning 0:
   - When start_value is NULL, query oldest weight from last 90 days
   - Prevents progress = 0% when start equals current

2. focus_areas_weighted_json empty:
   - Changed from goal_utils.get_focus_weights_v2() to scores.get_user_focus_weights()
   - Now uses same function as focus_area_weights_json

3. Implemented 5 TODO markdown formatting functions:
   - _format_goals_as_markdown() - table with progress bars
   - _format_focus_areas_as_markdown() - weighted list
   - _format_top_focus_areas() - top N by weight
   - _format_goals_behind() - lowest progress goals
   - _format_goals_on_track() - goals >= 50% progress

All placeholders should now return proper values.
