fix: RLS seeding, FQDN 422, stale migration hash, mail_accounts.password_salt

- Use migration engine (crm_migration, BYPASSRLS) for default data seeding
  in app/main.py instead of crm_api role which is RLS-enforced
- Skip domains PATCH for dockercompose apps in deploy_api() to avoid 422
- Regenerate migration_hashes.txt for 0085_restore_tenant_rls.py
- Add migration 0110: password_salt column to mail_accounts

app/main.py
