This commit addresses service discovery issues by explicitly configuring Consul DNS for the `openwebui` and `lobechat` tasks within the `ai-frontend` job.
Previously, services were unable to reliably resolve `ollama.service.consul`. This is resolved by:
* Setting `dns_servers` to the Consul server IP (`192.168.1.133`).
* Setting `dns_search` to `service.consul`.
* Reverting `OLLAMA_BASE_URL` and `OLLAMA_PROXY_URL` environment variables to use `ollama.service.consul` as intended.
* The `lobechat` task's image is now pinned to `v1.143.0` for improved stability.
* Removed outdated comments regarding host pinning.
