Bazel container fixes for runtime parity.

Whats New

1.0.53-pre19

• Enforced pure Go mode in Bazel so every shipped binary is static and CGO-free.
• Layered Alpine ping, nmap, and netcat APKs into all OCI images that expect those tools at runtime.
• Rebuilt the Bazel OCI targets to match the previously working docker-compose images.
