Add session indicator to issues in "My work"

### Feature summary

Make it easier to find issues that are not being worked on yet with a session indicator

### What problem are you trying to solve?

Issues come into the repo, I start investigating them from "My work". However, it's not possible from the my work view to tell which issues are being worked on in sessions and which are not.

Once a session has been started for an issue, I'd like to see that in "My work" and I'd like to jump from the issue to the session.

I realize this may be hard with multiple devs or same dev and multiple computers, but even showing this for just the local user/machine would be super helpful!

Beginne damit, die Ansicht „My work“ nachzuverfolgen und zu untersuchen, wie Sitzungen für den lokalen Benutzer oder Rechner dargestellt werden. Als abgeschlossen gilt die Aufgabe, wenn Issues in „My work“ sichtbar eine aktive Sitzung anzeigen und einen Weg vom Issue zu dieser Sitzung bieten, einschließlich des vorgesehenen Verhaltens für mehrere Entwickler oder Computer.
