feat(webui): migrate /runs list to unified design system (#1637)

Move runs.html from pageTemplates to standalonePageTemplates.
Rewrite template using w-* design system classes (w-nav, w-container,
w-page-header, w-filterbar, w-list) instead of layout sidebar + wr-*
classes. Preserves all JS: running section collapse, client-side search,
infinite scroll, child run rendering, model tier badges.

Closes #1634
