[Bug Report] Deny action notification on timeout, doesn't mention domain, and leads nowhere

### Describe the bug:
If the timer runs out, OpenSnitch will create a system tray notification. This notification, at least in case of a Deny rule, only mentions the commandline of the executable, but not the domain that was blocked.

Also, clicking that notification doesn't lead to the denied event (or even better, to the rule that resulted in denial).

Include the following information:
- OpenSnitch version: 1.7.2
- OS: Ubuntu
- Window Manager: KDE 6

### To Reproduce:

Steps to reproduce the behavior:
1. Configure the automatic rule to Deny after X seconds
2. Access a new domain
3. Wait X seconds
4. Inspect the notification pop-up

### Expected behavior (optional):
The notification should display the domain first, then the CLI.
Clicking it should lead to that event in the list.

Also, a MAJOR usability improvement would be the ability to navigate from an event to the rule that created it. #1337
