fix(config): use dataplane container names in service URL defaults

The homelab is retiring *.schweitz.internal and will rebind most
published container ports from 0.0.0.0 to 127.0.0.1 (Phase 4), so
host-IP:published-port URLs will stop working for container-to-container
traffic. Point the .env.example defaults at docker-dataplane container
names and INTERNAL ports instead: wiki:3000, neo4j:7687, searxng:8080
(internal port, not the 8087 host publish), paperless:8000, ollama:11434.
All names and ports verified against the running containers.

Also correct the AGENTS.md deploy health-check URL, which claimed the
service runs on port 8000; it runs on 8089.

static/wikijs-integration.js is left unchanged: it already derives the
API base from its own script URL (document.currentScript.src, split on
/static/) and only uses the hardcoded IP:8089 as a last-resort fallback.
