fix: Phase 0b - fix blood_pressure and top_goal_name bugs

Final bug fixes:
1. blood_pressure_log query - changed 'date' column to 'measured_at' (correct column for TIMESTAMP)
2. top_goal_name KeyError - added 'name' to SELECT in get_active_goals()
3. top_goal_name fallback - use goal_type if name is NULL

Changes:
- scores.py: Fixed blood_pressure_log query to use measured_at instead of date
- goal_utils.py: Added 'name' column to get_active_goals() SELECT
- placeholder_resolver.py: Added fallback to goal_type if name is None

These were the last 2 errors showing in logs. All major calculation bugs should now be fixed.
