feat(db): idempotent migrations + auto-deploy on startup

- Rewrite 0000_init with IF NOT EXISTS on all tables, indexes and enums;
  wrap FK constraints in DO/EXCEPTION blocks so re-runs never fail
- Add missing suggestions table to init migration
- Add migration 0002 to create message_logs table (IF NOT EXISTS)
- Add entrypoint.sh: runs prisma migrate deploy before starting the server
- Update Dockerfile to copy entrypoint.sh and use it as CMD
- Add prisma:migrate script to package.json for manual runs
