Wrong public WOPI url when collabora runs with non-empty net.service_root

[rriemann]

Describe the bug

Our organisations only allows traffic through one webproxy domain to reach the containers such as nextcloud and collabora.

Hence, we have the two containers exposed like this:

• https://inbound-gate.com/department/nextcloud
• https://inbound-gate.com/department/collabora

On top, the k8s cluster sets up an internal network, so that the containers can talk directly to each other.

Collabora container has set:

extra_params: --o:ssl.enable=false --o:ssl.termination=true --o:ssl.ssl_verification=false --o:fetch_update_check=0 --o:user_interface.mode=tabbed --o:remote_font_config.url=[…]/fonts.json --o:net.proto=IPv4 --o:net.service_root=/department/collabora

server_name: inbound-gate.com:443

To Reproduce

php occ richdocuments:setup --wopi-url http://$COLLABORA_SERVICE_HOST:$COLLABORA_SERVICE_PORT/edps/collabora --callback-url http://$NEXTCLOUD_SERVICE_HOST:$NEXTCLOUD_SERVICE_PORT/edps/cloud

php occ config:list richdocuments

Notice that the public_wopi_url is https://inbound-gate.com instead of https://inbound-gate.com/department/collabora

Expected behavior

The public_wopi_url is https://inbound-gate.com/department/collabora

Version of the richdocuments app

8.5.6

Version of Collabora Online

24.04.9.1

How to fix this

I believe the problem comes from here:

https://github.com/nextcloud/richdocuments/blob/3dbbe03d4e6a5cf5b0dacc584b3ce47973ab28c8/lib/Service/ConnectivityService.php#L58-L61

Excerpt:

		$determinedUrl = $this->parser->getUrlSrcValue('application/vnd.openxmlformats-officedocument.wordprocessingml.document');
		$detectedUrl = $this->appConfig->domainOnly($determinedUrl);
		$this->appConfig->setAppValue('public_wopi_url', $detectedUrl);

Instead of extracting domainOnly, also the path needs to be extracted.
