Lucky 11e1e22882 fix(docker): bump Go builder image to 1.26.6 to match go.mod
89d826be2 raised backend/go.mod to `go 1.26.6` and updated the three CI
workflows' version assertions, but left the Go builder image in all three
Dockerfiles pinned at 1.26.5. Since the official golang images set
GOTOOLCHAIN=local, the toolchain is not auto-downloaded and any image build
fails hard at `go mod download`.

CI does not catch this: the workflows build with actions/setup-go, not with
these Dockerfiles.

Also extend the Go-upgrade checklist in DEV_GUIDE.md, which listed only the
CI files -- that omission is why the Dockerfiles were missed.
