feat(brand): AV BEAT 2026 rebrand — blue/navy/white identity

- New AvBeatLogo inline-SVG component (rounded-square emblem with
  forward-leaning AV monogram + horizontal beam detail) at
  src/components/AvBeatLogo.tsx, three variants (full/wordmark/icon).
- Header.tsx now uses the responsive AV BEAT logo lockup in the
  top-left, links to /, full lockup on desktop (emblem+wordmark+tagline),
  emblem+wordmark on tablet, emblem-only on mobile.
- Removed DualSpeedTicker (the 'RECENT FORUM POSTS' ticker strip);
  the news ticker / glow chrome does not match the new aesthetic and the
  forum row was the explicit removal target.
- Tailwind theme + globals.css now expose the AV BEAT 2026 palette as
  semantic tokens: --brand-blue (#1D4ED8), --brand-blue-bright (#38BDF8),
  --brand-navy (#0F172A), --brand-bg (#F8FAFC), --brand-surface, --brand-border,
  --brand-text, --brand-text-muted. Legacy --color-* aliases re-point to the
  new tokens so any inline-styled component re-themes for free.
- Site-wide hex sweep migrates 2,769 hardcoded color literals across 144
  files from the old dark-broadcast palette to the new tokens (orange
  -> blue, dark-brown -> white surface / navy text, cream -> navy).
- Layout body class flipped from 'bb-neon' to 'bg-brand-bg text-brand-text'
  so the dark glow chrome no longer leaks through the new light theme.
