ssh: Add session state indicator to title bar (#18645)

![image](https://github.com/user-attachments/assets/0ed6f59c-e0e7-49e6-8db7-f09ec5cdf653)
The indicator turns yellow when ssh client is trying to reconnect. Note
that the state tracking is probably not ideal (we'll see how it pans out
once we start dog-fooding), but at the very least "green=good" should be
a decent mental model for now.

Release Notes:
