Implement comprehensive analytics redesign with bot detection and charts

- Add bot detection logic to differentiate between real traffic and bot traffic
- Detect common bots: search crawlers, social media crawlers, headless browsers, monitoring tools, security scanners
- Expand hit-stats.json to track realHits, botHits, byPathReal, byPathBot, byDayReal, byDayBot, botReasons
- Update analytics API endpoint to return bot/visitor breakdown with 7-day and 30-day comparisons
- Add Chart.js integration with react-chartjs-2 for interactive visualizations
- Create new AnalyticsPanel component with tabbed interface: Overview, Bot Breakdown, Geographic
- Implement graphs showing: 7-day trend (real vs bot), traffic composition (doughnut), bot sources (pie), top pages (bar)
- Display clear KPI cards showing real traffic %, bot traffic %, return visitor rate
- Add deployment & cache status section to analytics dashboard
- Improve data presentation with responsive grid layouts and color-coded metrics
