Refactoring code in src/notification.js of NodeBB

[tatougueye]

Refactored the notification system to improve code readability and maintainability by breaking down large functions into smaller, reusable ones. Specifically refactored 2 functions: 'notifications.Each' and 'differentiators.forEach'. Removed redundant logic and streamlined the process for sending notifications and emails. All functionality has been tested through existing unit tests and manual verification. resolves #11
