chore: simplify email-worker Docker setup

Remove private registry references and SSH key handling from Docker
build process. Images now build locally without registry prefix.

Changes:
- Remove SSH key copying from Dockerfile (no private npm packages)
- Remove registry.ngit.hr references from build and run scripts
- Simplify image tags to local format (no registry prefix)
