ci: diagnose e2e audit_logs mystery; fix docker-deploy admin seed

- e2e: install psql; dump 'getent hosts postgres' (suspect two hosts
  answer to 'postgres' on gitea_gitea) and the table list after push.
  Fail loudly when audit_logs is missing so we see the true state at
  push time instead of later at seed time.
- docker-deploy: setup-admin.mjs imports @prisma/client via bare
  specifier, which only resolves inside packages/db in pnpm workspaces.
  Run the script through `pnpm --filter @capakraken/db exec` so Node
  walks the right node_modules.
