Subject: [PATCH] fix(docker): copy go.sum so the server image builds

deployments/docker/Dockerfile copied only go.mod into the build stage,
so `go build` failed with:

  missing go.sum entry for module providing package gopkg.in/yaml.v3
  (imported by github.com/alibaba/UnifiedModel/internal/umodel)

Copy go.sum alongside go.mod and run `go mod download` before building,
the standard multi-stage Go pattern.
