Publications: drop dividers between papers; one-line layout when no thumb

- Remove the dotted border-top between publications inside a year group.
- For pubs without a thumbnail, collapse authors / title / journal /
  links into one inline-flowing paragraph (matching the original site's
  typesetting). Pubs with a thumbnail keep the two-column layout.
