Complete Notification Page Functionality (Frontend)

[ctc-devops]

Authors:

What does this PR contain?

• Notifications are sorted and grouped by day
• Approving an account removes the entry from the list & displays a toast.
• Notification list displays newly-confirmed and newly-added events

How did you test these changes?

• Run this front-end branch 36-complete-notification-page-functionality-frontend locally with backend from branch #45-notification-page-functionality.

Attach images (if applicable)

• The notification button and drawer will be placed in the layout navbar, so http://localhost:3000/notification-sandbox will temporarily have a working demo of the notification page.

• Clicking the bell icon opens the drawer
  

• Multiple pending accounts notifications in the same day will be grouped into the same day. Event notifications in the same day are separated.
  

• Toast Notifications
  
  
  
  

Additional Notes

• The Figma hi-fi suggests to group notifications by hour (instead of days) if they occur in the last 24 hours. A bit of work beyond the scope of this issue may be required.
• The current user schema doesn't support full names so emails were only used instead.

Closes #36
