fix: fullscreen toggle loads correct session instead of default

When toggling fullscreen, the iframe reload was reading the session name
from the node's widget (default "my_session") instead of the session
the user had actually selected in the Dashboard picker.

Now the Dashboard sends its current session name in the fullscreen
postMessage, and the handler prefers that over the widget default.
