feat: add user preference for audio notifications and play sound on new alerts

- Added sound_enabled column to users table with a default of true.

- Implemented a pleasant pop sound (notification.mp3) that plays when a new unread notification arrives.

- Added a toggle in the User Profile page allowing users to enable/disable the sound.
