refactor: redesign UI — article title at top, fix list display, larger fonts

- Move article title/source/meta OUT of player into .brief-now-playing section at top
- .brief-player now contains only wave canvas + play button (prevents overflow issue)
- Increase font sizes: title 18→20px, list 13→14px, top bar 13→14px
- Add HTML escaping (esc()) in renderList to prevent XSS/broken layout
- Fix skip() to use articles.length (not speechQueue.length) for bounds
- Guard updateListHighlight against null querySelector results
- Remove defer from inline script (ignored for inline scripts, was misleading)
- Add border-top to brief-list for clear visual separation
