Adds a "Mark as unread" option to the notification popup menu (shown only
for already-read items) and a swipe-right gesture, mirroring the existing
"Mark as read" actions. Swipe/menu actions respect the active filter:
items are removed from the list only when filtered to New or Old, and
snap back when viewing All.

Users can now mark a notification as read via a popup menu on each list
item or by swiping left. Both actions call the backend API, remove the
item from the list, and show a snackbar confirmation. Swiping an already
read notification shows an error snackbar and bounces the item back.
