feat(avbeat): typography phase-1 slice + drop homepage Topics chip row

Typography (approved Phase 1 slice only — utility classes + other reclasses deferred):
- src/styles/tailwind.css body rule: re-add smoothing now that the surface palette is locked in — -webkit-font-smoothing antialiased, -moz-osx-font-smoothing grayscale, text-rendering optimizeLegibility, font-feature-settings 'kern','liga', global letter-spacing -0.005em.
- src/components/FeaturedBentoFromDb.tsx:115 cinematic hero headline: text-2xl md:text-4xl lg:text-5xl leading-tight → text-[40px] md:text-[48px] lg:text-[56px] leading-[1.05] tracking-[-0.02em] font-bold. Confident editorial display per the avinteractive reference.
- src/app/news/[slug]/NewsArticleDetailClient.tsx:309 and src/app/articles/[slug]/ArticleDetailClient.tsx:255 article H1: text-[#f0f0f0] → text-[#0F172A]. Fixes the leftover white-on-white readability bug on article pages.

UI:
- src/app/home-page/components/ArticleFeed.tsx: removed the 'Topics:' chip row from Industry News per current design direction; all stories now show without per-topic filter.
