Fix ImportError: replace _normalize_name_text import in trajectory_model.py

Phase 1C removed _normalize_name_text from pitcher_adjustment.py but
trajectory_model.py was still importing it directly from there, causing
a startup crash on HF Spaces. Now imports normalize_pitcher_name from
data.odds_name_map aliased as _normalize_name_text so internal usage
lines are unchanged.
