feat(a11y): add aria-live region to editor save status indicator (#1138)

Add a screen-reader-only role="status" span inside the editor save status
container. Only terminal states (Saved, Save failed) are rendered in the
live region to avoid noisy announcements from transient Saving... updates
on every keystroke.

Follows the existing RowCountAnnouncer pattern for live regions.
