db: Drizzle schemas on domain Postgres schemas, baseline migration, reorg SQL

- pgSchema tables for auth, money, house, ref, games, cs, animaldex, site, meta
  (lists excluded via schemaFilter; runtime list tables are managed by meta.*)
- drizzle/ baseline matches the reorged DB exactly (catalog diff = 0 on rehearsal)
- db/reorg: one-time SQL that moves the flat public schema (rehearsed on a prod copy)
- scripts/db-migrate.ts: migrator with --init to record the baseline and a guard
  against running the baseline on a non-empty, unrecorded database
