Updated: Improve monitor deletion flow with toast notification

- Added functionality to retrieve and display a toast message from localStorage
  after the page reloads, triggered by a successful monitor deletion.
- Modified the `deleteSelected` method to immediately refresh the page after
  deleting selected monitors and store the response for the toast notification.
- Cleaned up localStorage after showing the toast to avoid repeating the message.
