Unify publisher plugin database setup and migration paths

- Make Drizzle migrations the single source of truth, replacing dual
  raw DDL + Drizzle paths in setup.js
- Auto-run migrations on plugin startup (zero manual steps for updates)
- Add bootstrap guard for databases created by old setup.js (seeds
  __drizzle_migrations journal so Drizzle can take over)
- Fix migration 0001 FK incompatibility: change PKs from serial
  (BIGINT UNSIGNED) to int AUTO_INCREMENT to match int FK columns
- Add 0002 migration for error_details column and private_key rename
- Fix migration folder path resolution for tsup flat bundle output
- Improve setup.js: hide password input, fix Mode 1 config overwrite,
  replace raw DDL with migrate(), update wording
- Add structured error details to publishing attempts
