fix(docker): copy and build @openwork/email package for den-api image

[yashranaway]

Closes #1804

Summary

• Copy packages/email/package.json into the den image before pnpm install --frozen-lockfile so the workspace package resolves.
• Copy the packages/email source after install and add a build step before den-db and den-api so the compiled dist/ exists when den-api imports @openwork/email at runtime.
• Keep the existing build order otherwise unchanged; @openwork/email has no workspace deps so it can build right after utils.

Verification

• docker build -f packaging/docker/Dockerfile.den . not run from this branch (no Docker on the dev box); the diff matches the exact patch the reporter posted in the issue.
• grep '@openwork/email' ee/apps/den-api/package.json confirms den-api lists the workspace dep, and packages/email/package.json exports ./dist/index.js as the production entry, which makes the missing build step the failure path described in Dockerfile.den missing @openwork/email package — build fails #1804.

Notes

• packages/email has no workspace dependencies, so it can build independently of den-db.
