Fixes #1487

Requires go 1.26.10 in go.mod (go install ignores toolchain) so builds include the CVE-2026-111943 fix (golang/go#82345).

Pin both release builder images to Go 1.26.10.

go.mod requires Go 1.26.10, but the floating golang:1.26-alpine3.24 tag currently provides Go 1.26.9 and sets GOTOOLCHAIN=local. Both release builds can therefore fail at go mod download.

Suggested fix
# .github/docker/client/Dockerfile
-FROM golang:1.26-alpine3.24 AS builder
+FROM golang:1.26.10-alpine3.24 AS builder

# .github/docker/server/Dockerfile
-FROM golang:1.26-alpine3.24 AS builder
+FROM golang:1.26.10-alpine3.24 AS builder

Review comment at @go.mod at line 3:
Pin the builder base image in both release Dockerfiles to the exact Go 1.26.10
Alpine tag, replacing the floating golang:1.26-alpine3.24 reference in each
builder stage.
