The CI server can't reach dl-cdn.alpinelinux.org (TLS error) — only the Nexus mirror is reachable, and it proxies Docker images, not apk packages. - frontend: drop `apk add libc6-compat` (vestigial Next.js-template line; the deps stage only runs `npm ci` and the build/runtime stages never had it). - 5 Go services (file/gateway/notification/payment/render): replace `apk add ca-certificates tzdata` with copying ca-certificates.crt from the golang builder stage + embedding tzdata via `go build -tags timetzdata`. No more apk -> no dependency on the Alpine CDN. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
