- Phase_64_002: Convert to closure-based migration with column existence checks
  (was failing because movement_type already existed from partial prior run)
- Phase_65_012: Backtick-quote `row_number` (MySQL 8.0 reserved word)
- Phase_64_001 seed: Use description_ar instead of non-existent description column,
  remove is_active (not in schema), add config_type and group_name
