fix(docker): remove overwritehost to fix container-to-container DCR

Browse Source 
Remove the overwritehost and overwrite.cli.url settings that were forcing
Nextcloud to generate URLs with localhost:8080 regardless of the incoming
request's Host header.

This was breaking Dynamic Client Registration (DCR) from the mcp-oauth
container, which needs to reach Nextcloud at http://app:80 but was getting
discovery documents with http://localhost:8080 URLs that are unreachable
from inside the Docker network.

Now Nextcloud respects the Host header:
- Browser requests to localhost:8080 → returns localhost:8080 URLs
- Container requests to app:80 → returns app:80 URLs
