fix: notification items are now real links (#2039)

Replace UnstyledButton with UnstyledButton component={Link} so each
notification renders as a real anchor element. Regular left-clicks use
SPA navigation and close the popover; Ctrl/Cmd/middle-click open the
page in a new tab. All click types mark the notification as read.
