List ~/.ssh/config hosts in the panel source dropdown

Read-only group below saved connections; hosts resolve HostName/User/
Port/IdentityFile (Include, wildcards, %-tokens) and connect on click.
New ssh-agent auth kind covers hosts without a usable identity file;
ProxyJump/ProxyCommand hosts are shown disabled.
