Fix submission row aria-labels for WCAG 2.1 AA compliance

Apply descriptive aria-labels to all focusable elements in _submission.html.erb:
- Status badge links: "Document Status: [status]"
- Submitter name links: "Submitted by: [submitter]"
- Edit pencil (icon-only): "Edit [document-name]"
- Sign Now button: "Sign this document"
- View link: "View document"
- Archive button: "Archive [document-name]"
- Overlay cover link: aria-hidden + tabindex=-1 (removes duplicate focus trap)

Covers both single-submitter and multi-submitter layout variants.
