Notifications pop-up keep appearing even after disabling notifications

### Steps to reproduce

1. Where are you starting? What can you see?
Install Element desktop on Ubuntu 26.04
Disable notifications via Settings > Notifications > Element > slide "Notifications" to the left

Notifications keep appearing, even after restarting Element and restarting the OS.

### Outcome

#### What did you expect?
Possible to turn notifications off, but this is not possible on Ubuntu 26.04.

After some sparring with Claude AI, it is only a packaging issue and not an issue of Element (core).
There seems to be some confusion between an `element.desktop` and `element-desktop.desktop` apps. The OS is listening to the latter but only the former is being triggered in some way.

Workaround for now:
```
ln -s /usr/share/applications/element-desktop.desktop ~/.local/share/applications/element.desktop
update-desktop-database ~/.local/share/applications/
dconf write /org/gnome/desktop/notifications/application/element/enable false
```
(or write your specific desired notifications settings)
Power cycle/shut down and open Element Desktop.
