Fix CI build and update Makefile to build all services

- Add $HOME/go/bin to PATH using $GITHUB_PATH for protoc plugins
- Update Makefile build target to build all service binaries:
  - platform, api-gateway, auth-service, identity-service, authz-service, audit-service
- Update CI workflow to use 'make build' instead of individual commands
- Upload all service binaries as CI artifacts
- Fixes protoc plugin discovery and ensures all services are built
