[BUG] Support file / packet capture download times out — port 28082/tcp missing from example docker-compose.yml

Start with the example docker-compose.yml used in the image documentation and review its published ports. Add the port mapping for 28082/tcp, then deploy the example and verify that support file and packet capture downloads complete successfully.

Is there an existing issue for this?

Current Behavior

When using the example docker-compose.yml as provided in the image documentation, trying to download a "Support File" or a packet capture from the UniFi Network Application web UI fails with a timeout.
This happens because the controller serves these downloads over port 28082/tcp, which is not exposed/mapped in the container's port list.

Expected Behavior

Support file and packet capture downloads should complete successfully.
Port 28082/tcp should be included (at least as an optional mapping, similar to 1900, 8843, 8880, etc.) in the example docker-compose.yml so users aren't left without a working download feature.

Steps To Reproduce

1. Deploy the container using the example docker-compose.yml as provided in the documentation.
2. Log into the UniFi Network Application web UI.
3. Go to UniFi Device > Select device -> Settings and click "Download support file" (or attempt to download a packet capture in Airview - Select WiFi band - packet capture).
4. The download request hangs and eventually times out.
5. Add 28082:28082 to the port mappings and restart the container — the download now works.

Container logs

"docker logs unifi-app" shows nothing relevant, the application container itself starts and runs normally, no errors logged there:
[ls.io-init] done.

However, on the UniFi AP side (via SSH), the following error appears when attempting the support file upload/download:

Sat Sep  5 12:08:20 2026 user.notice syswrapper[17997][5474]: Failed to upload support file. Http code: 000, rc: 7

"rc: 7" corresponds to curl's "Failed to connect to host" error, and "Http code: 000" confirms no HTTP response was ever received — consistent with port 28082/tcp not being reachable, since it isn't published in the container's port mapping / not allowed through the firewall.
