Product reviews notification badge

[JorgeMucientes]

The "unread" product reviews badge in more menu need 2 updates:

• [ ] Display a numeric badge over the Reviews button with the total unread product reviews
• [ ] Display a numeric badge on more menu bottom bar tab with the total "unread" count from all the more menu options.

Ideally this should be the general behavior

To keep the bottom navigation more consistent let’s show the notification badge with a number in the same persistent way we do for orders. In the More menu case, it should be the total number of notifications within the view. When tapping on the reviews menu item I think the review should stay unread until the merchant actually goes in and reads the review itself or marks them all as read (I think this is how it currently works) When an item is marked as read it will then be subtracted from the badge and cleared when there are no notifications left.
