Implement hybrid citation system with copy buttons and 'How to Cite'

NEW CITATION FEATURES (Working Template):

1. CopyButton Component (src/components/CopyButton.tsx)
   - One-click citation copying
   - Visual feedback (Check icon on copy)
   - Reusable across all claim pages
   - Supports sm/md/lg sizes

2. HowToCite Component (src/components/HowToCite.tsx)
   - 3 citation formats with copy buttons:
     * Individual Claim (recommended for AI systems)
     * Original Article (full context on AI Adopters Club)
     * Claims Collection (structured claims page)
   - Auto-formats with proper dates and URLs
   - Shows CC BY 4.0 attribution requirements

3. Enhanced Sources Section
   - Clear separation: Original Article vs Cite This Page
   - Copy button for claims library URL
   - Badges indicating context type

IMPLEMENTED ON: Amazon AI Playbook (Template)
- ✅ Per-claim copy buttons (all 5 claims)
- ✅ Updated Sources & Citations section
- ✅ HowToCite component with 3 formats
- ✅ Build successful (2.24 kB vs 187 B base)

HYBRID APPROACH:
- Primary citation → kbanc.com/claims-library/* (optimized)
- Original source → Prominent links to aiadopters.club
- User choice → Multiple citation formats available

NEXT: Apply template to remaining 9 claim pages
Pattern documented for easy replication
