Subject: [PATCH] refactor(nomad): Centralize DNS configuration for AI
 frontends

Moves DNS server and search domain configuration from task `config` blocks to the job/group `network` blocks for `ai-frontend` (OpenWebUI) and `lobechat`.

This refactoring centralizes DNS settings for all tasks within a Nomad job or group, ensuring consistent DNS resolution and aligning with recommended Nomad configuration patterns.
