Describe the Bug

The dashboard can be accessed at pangolin.example.com.
If you configure the same subdomain as a resource, you will be redirected in a loop (HTTP 302).

I configured it this way on purpose to test whether anything would break, and it did. :)
I don't think that's a common issue.

I fixed it by changing the dashboard's subdomain in the configuration; you can then remove the resource.

Environment

OS Type & Version: Debian 13
Pangolin Version: 1.16.2
Gerbil Version: 1.3.0
Traefik Version: 3.6

To Reproduce

Setup Pangolin on pangolin.example.com
Add local site
Create public resource
- HTTPS Settings
  - Subdomain pangolin
  - Base Domain example.com
- Targets Configuration
  - Local site
  - Protocol https
  - Host localhost
  - Port 443

Expected Behavior

There should be a warning or error message.
