fix(right-wing): update DB with latest motions, fix DROP TABLE bug, score all missing 2D

- Fetched 276 new motions from Tweede Kamer API (2026-04-23 to 2026-05-31)
- Fixed classify_motions.py: DROP TABLE → CREATE TABLE IF NOT EXISTS
- Restored derived columns (centrist_support_strict, category, etc.) via migration
- Scored 180 missing motions in extremity_scores_2d (now 3,049 total, 0 missing)
- Re-ran temporal trajectory with updated data (inflection: 2024-Q2)
