[Bug Report] Settings Dialog Apply and Save button problems

### Describe the bug:

The Settings dialog always causes an eBPF load error to appear, where opensnitch.o cannot be loaded when you click on the "Apply" button.

### How to reproduce

- Start opensnitch-ui
- Open Settings dialog
- Open Nodes view
- Open General tab
- Change "Default action when the GUI is disconnected" to "drop"
- Enable "Debug invalid connections"
- Click Apply

However, if you do the exact same thing, and click the "Save" button, it will successfully save the modified settings. If you then close the Settings dialog, open the same view/tab, and just click "Apply" in that new dialog, it works without a problem and seems to apply the correctly changed settings.

If you click only on Apply and close the Settings Dialog afterwards, it will not change the settings. Opening the Settings dialog again will show the old/unchanged settings.

Start by reproducing the issue in opensnitch-ui through Settings > Nodes > General, comparing Apply with Save after changing the default disconnected action and enabling debug invalid connections. Trace the Apply and Save paths and the eBPF load error; done means Apply updates and persists the settings without the opensnitch.o error, including on a freshly opened dialog.
