ticker: replace LiveWire with dual-row neon ticker (news + events)

Row 1 (Live Wire, scrolls →): most recent imported + AI-rewritten
articles, neon-green label, monospaced [HH:MM] [SOURCE_CODE] prefix.
Row 2 (On Calendar, scrolls ←, slower): upcoming events from
bb.events (confirmed/tentative, start_date >= today), neon-cyan
label, [Mon DD] [SHORT_NAME] prefix.

Defensive: each query is in its own try/catch so a partial failure
renders an empty row rather than crashing the page — that was the
silent build crash that took down the prior DoubleTicker incarnation.
If BOTH queries return zero rows we render nothing instead of two
blank bars.

CSS tokens added to redesign-tokens.css:
- bb-marquee--reverse + bb-marquee--slow modifiers
- .bb-neon-bar / .bb-neon-label / .bb-neon-time / .bb-neon-code
  (scoped class names so this is the ONLY place on the site that
  uses the neon palette — rest of the site keeps dark-navy + blue)

User cancelled the wholesale neon redesign; only the dual-ticker
keeps the neon green/cyan styling.
