ZGaetano f5abf359fb fix(nginx): use Docker embedded DNS resolver to avoid startup DNS failure
nginx resolves upstream hostnames at config load time, which fails when
sibling containers haven't registered with the Docker DNS yet. Using
resolver 127.0.0.11 with set $upstream defers resolution to request
time, preventing the "host not found in upstream" startup crash.
