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.
