Add Analytics and Event Tracking

[gboigwe]

No analytics tracking is implemented, making it hard to understand user behavior and improve the platform.

Goal:

• Integrate analytics provider (Mixpanel, PostHog, or Plausible)
• Track key user actions:
  • Wallet connection/disconnection
  • Event creation and ticket purchases
  • Connection requests sent/accepted
  • Message sending
  • Network switching
• Add page view tracking
• Create analytics utility hooks

Implementation:

• Create apps/web/src/lib/analytics.ts utility
• Create useAnalytics hook
• Add tracking to all user actions
