fix: convey summary status in Reading Level card accessible name

The Reading Level summary card visually displays a status such as
'Summary required', but its aria-label only announced the reading
level (e.g. 'View reading level details: 12th'), so screen reader
users never received the visible status. Include the summary status
in the card's accessible name when one is displayed.

Fixes #1765
