feat(04-07): migrate list_items.rank to COLLATE utf8mb4_bin (LIST-03)

- Add varcharBin customType helper emitting varchar(255) COLLATE utf8mb4_bin
- Replace listItems.rank varchar with varcharBin to carry explicit binary collation
- Generate migration 0002_yielding_mattie_franklin.sql: ALTER TABLE list_items
  MODIFY COLUMN rank varchar(255) COLLATE utf8mb4_bin NOT NULL (additive, no DROP)
- Apply migration via db:migrate (never db:push, per project memory constraint)
- utf8mb4_bin ensures uppercase-prefixed ranks (e.g. Zz) sort before lowercase
  ranks (e.g. a0) in DB ORDER BY, matching JS string order — closes LIST-03 gap
