[Bug Report] Double-clicking table fields makes them editable, which doesn't make sense

### Describe the bug:
In most tabs, double-clicking table fields makes them editable. That's useful to copy text, but would it be possible to make the cells read-only?

What I was hoping to obtain by double clicking, was to show the Details popup, which isn't available in Hosts, Applications, Addresses, and Ports. Would be nice if Pressing Enter displayed it, but that doesn't work even in Events.

Include the following information:
- OpenSnitch version: 1.6.8
- Window Manager: KDE

### To Reproduce:

1. Go to 'Applications'
2. Double click on a cell in the 'Time' column
