feat: implement API usage tracking and admin dashboard
- Added database schema for API tracking system: * api_usage table - tracks all Google Search and Gemini AI calls * user_credits table - prepared for future credits system * admin_users table - controls admin dashboard access - Created comprehensive tracking service (track-api-usage.ts): * trackApiUsage() - records API calls with success/failure * checkDailyLimit() - enforces 80 Google Search calls/day limit * getUserApiStats() - per-user statistics * getGlobalApiStats() - app-wide statistics (admin only) * checkIsAdmin() - server-side authorization - Integrated tracking into discover-whiskybase.ts: * Pre-call limit checking with friendly error messages * Post-call usage tracking for success and failures * User authentication verification - Built admin dashboard at /admin: * Global statistics cards (total, today, by API type) * Top 10 users by API usage * Recent activity log with 50 latest calls * Color-coded status indicators * Secure access with RLS policies - Features: * Daily limit resets at midnight Europe/Berlin timezone * Graceful error handling (allows on tracking failure) * Comprehensive indexes for fast queries * Ready for future credits/monetization system
