Notifications: Add sound option to generic useNotification hook and code cleanup

[BackSH00TER]

Pull Request Description
Problem: When a user receives a notification, the alert does not play a sound effect.

I found that each app had its own implementation of a useAppNameNotification hook (ex: useMessageNotifications), that did have a sound option built in. I followed up with Chip in discord and he confirmed these hooks were from a previous older notification system and that they moved to a more generic approach using a single useNotification hook.

As such this PR does two things:

• delete the now obsolete app specific notification hooks (double checked they are not used anywhere in the codebase)
• update the generic useNotification hook to take a new parameter playSound
  • when true this will trigger the sound alert
  • the notification options were also typed as any so I added specific types for these so its more clear on the expected shape of the options
