🐛 Cannot use "Protect with Access" for SSH over browser tunnel.

**Describe the bug**
Setting up an SSH tunnel through the dashboard's "Application" section, I can't protect it with SSO. I'm running cloudflared with docker on the "host" network, which works for all other tunnels I have. Investigating this in Cloudflare Discord (thanks Chaika), we discovered that SSH Applications don't show in Public Hostname -> (select item) -> Additional Application Settings -> Access -> Protect with Access, which make protecting with Access an SSH terminal through a browser impossible.

**To Reproduce**
Create a Self hosted app that is a browser SSH tunnel to your server running cloudflared pointing at the sshd port (usually `localhost:22`). Then, create a public hostname and try to protect it with Access.

**Expected behavior**
The dropdown "Protect with Access" should have the SSH application available.

**Environment and versions**
- OS: ArchLinux
- Architecture: x86_64
- Version: _rolling release_
