silverwind 23a5bc5e64 Optimize Docker build with dependency layer caching (#36864)
1. Copy dependency manifests before the full source copy so that
dependency installation gets its own cached layer. When only source code
changes, the dependency layers are reused.
2. Remove the `GOPROXY=direct` override which was bypassing the Go
module proxy, causing build failures when git servers are unreachable.
The Go default (`https://proxy.golang.org,direct`) is now used instead.
