Subject: [PATCH] feat(build): add Docker support for emailks service

- Create multi-stage Dockerfile with builder and runtime stages
- Add .dockerignore to exclude unnecessary files and directories
- Configure builder stage with Rust toolchain and dependencies
- Set up runtime stage with minimal Debian base image
- Copy compiled binary from builder to runtime stage
- Expose port 50051 for gRPC service
- Add proper dependency caching for faster builds
- Include SSL certificates and required libraries in runtime
