fix(dashboard): use dynamic DNS resolution for API proxy

Browse Source 
Nginx caches DNS at startup, so when dashboard-api restarts and gets
a new container IP, the proxy breaks with 502. Use Docker's embedded
DNS resolver (127.0.0.11) with a variable-based proxy_pass to
re-resolve on every request.
