fix(docker): align standalone essentials network with full compose

[NKchinmayanandu]

Description

docker-compose-dev-essentials.yaml did not explicitly declare its default
network, causing standalone execution to create docker_default.

The full Compose configuration uses the explicitly named unstract-network,
and the essentials configuration already configures Traefik to use that network.

This change explicitly names the default network as unstract-network so the
standalone essentials configuration uses the same network as the full Compose
configuration.

Greptile Summary

This PR aligns standalone development essentials with the full Compose stack by explicitly naming its default Docker network.

• Adds a default network declaration named unstract-network.
• Matches the network expected by Traefik and other local container tooling.

Confidence Score: 5/5

The PR appears safe to merge.

The essentials configuration now uses the same explicit network name already expected by the full Compose stack, Traefik, and local container tooling, with no supported launch or teardown path shown to regress.
