Bug: ssh tunnel not closed after closing window

[eliottwantz]

What happened?

When connecting with a ssh tunnel proxy, and then closing the TablePro window for that connection, the ssh tunnel is still up. We can see that by checking the open ports for ssh.

Steps:

1. Open a connection with an ssh tunnel
2. Once connected and the TablePro window for that connection opens, close it
3. Check for open ports for ssh: lsof -i | grep ssh
4. Observe connection still established

Environment

0.15.0 / macOS 26.3.1 / Apple Silicon

I am going to sleep, and will have a PR open by tomorrow @datlechin

Note that #215 does not solve this issue, it's unrelated.
