- Add `prefix` param to checkRateLimit/getRateLimitHeaders so each endpoint
has its own bucket (previously all shared `admin_${ip}`, causing 429s when
analytics/track incremented past n8n endpoints' lower limits)
- n8n/hardcover/currently-reading → prefix 'n8n-reading'
- n8n/status → prefix 'n8n-status'
- analytics/track → prefix 'analytics-track'
- Remove custom analytics system (AnalyticsProvider, lib/analytics,
lib/useWebVitals, all /api/analytics/* routes) — was causing 500s in
production due to missing PostgreSQL PageView table
- Remove analytics consent toggle from ConsentBanner/ConsentProvider
