feat(04-01): add list tables to schema and apply via generate+migrate [BLOCKING]

- Append lists, list_shares, list_items tables to Drizzle schema (schema.ts)
- lists: owner_id FK, is_shared bool default true (D-01), idx_lists_owner_id
- list_shares: list_id + user_id FKs, uniq_list_share, idx_list_shares_user_id (D-02)
- list_items: rank varchar for fractional-indexing (D-13), checked bool, composite indexes
- Generate 0000_easy_slipstream.sql (full schema baseline) + 0001_lists_schema.sql (new tables)
- Mark 0000 as applied in __drizzle_migrations (prior tables existed from manual DDL)
- Apply 0001_lists_schema.sql via db:migrate — lists/list_shares/list_items now in MariaDB
- Add vitest/globals + node to tsconfig types for test file compatibility
- NEVER used db:push (hard project constraint — drizzle-mariadb-push-unsafe)
- typecheck passes
