chore(web): refresh visual baseline(s) (blog)

Manually triggered baseline refresh via
.github/workflows/refresh-visual-baselines.yml on branch
fix/bot-2716-paginationnav-default-anchor-display-ux-differs-fr.

Run when an intentional content/layout change makes the visual-regression
check fail. The new PNG(s) under web/tests/visual-baselines/ are now the
expected rendering; re-run the failing visual-regression job to flip the
check green.
