Evolution Ignore desktop DND mode + no GUI to switch it off

[cm-t 🦄🏂🌈🎵]

Hi,

On Ubuntu 22.04 LTS:

 * I open gnome-shell top notification menu, it shows time, and notification list, and also a button to disable notifications.
 * I click the "do not disturb" button to make sure there is no notification during my game
 * I launch a game in full screen
 * Wait time of a calendar event
 * Fullscreen Game will be reduced to desktop, and the evolution calendar windowed notification alarm will appears.

There are 2 issues here:

 * Evolution calendar could have a built-in setting to allow this intrusive pop-up that can't be disabled by GUI it seems
 * In case desktop DND mode is exposed to apps, this popup should check before if DND is ON, then just not disturb me :)

The only current way to dodge it for now, is to disable all calendar or uninstall evolution …
