Add Audio Alarm when alert is recieved

[fe51]

Pitch

Firefighters have regularly asked us to have the option of an audio alarm on the platform when a new alert is received.

However, some of them do not want an audio alarm.

Would be great to have a button to activate/deactivate alert sound.

Suggestion

• Add a button (maybe a toggle button ? Do not know exactly, open to suggestions) in the top right corner of the main page (at the left of the langage button when Basic basic multilingual management #171 will be done ) (idem, open to the location that seems most relevant -> see screenshot below)
• Maybe the best scenario is to have it activated by default (and those who will be annoyed can deactivate it)
• About the sound itself, open to suggestions :)

As a first version of this feature, because saving the default preference would imply saving the info in our backend, we could consider it is okay that, we get (or maybe it can be stored in web cache ?)

Happy to discuss it & thanks a lot 🙏 🎆
