SSRF to the internal KV store

Network & Infrastructure Difficulty ~10 min +10 XP

This health-check fetcher has a guard: it blocks external hosts but happily allows loopback, because "only internal services live there." That assumption is the bug. Probe the loopback interface, follow the hint the server leaks when you knock on the wrong door, and pull the flag out of the internal key-value store it points you to.
