fix(config): use docker hostnames for tatlock and searxng defaults

The homelab is retiring *.schweitz.internal and will rebind host ports
to 127.0.0.1, so container-to-container traffic must use container
names on the docker-dataplane network. Switch defaults from host
IP:port to http://tatlock:8000 and http://searxng:8080 (SearXNG's
internal port is 8080; 8087 is only the host-published port).
