Upgrade miekg/dns and x/crypto to resolve known CVEs

[Copilot]

Several known vulnerabilities in transitive and direct dependencies, including a critical CVE in golang.org/x/crypto and a moderate one in github.com/miekg/dns.

Dependency changes

• github.com/miekg/dns: v1.1.4 → v1.1.62 — fixes CVE-2019-19794 (Moderate)
• golang.org/x/crypto: v0.0.0-20190222235706 → v0.25.0 (now transitive) — fixes CVE-2024-45337 (Critical), CVE-2020-9283, CVE-2020-7919, CVE-2022-27191, CVE-2021-43565 (all High)
• golang.org/x/net, golang.org/x/sync, golang.org/x/sys: bumped to current versions via go mod tidy

golang.org/x/crypto is no longer a direct dependency of this module — the updated miekg/dns no longer requires it directly, but it remains in the build graph at a secure version.
