- Fixed app/api/leaderboard/user/[userId]/route.ts.backup: Converted to lazy initialization
- Fixed app/api/leaderboard/stats/route.ts.backup: Converted to lazy initialization
- Fixed lib/seo/metadata.ts: Removed unused verification environment variables
- Updated all database service functions in AI route to use getSupabaseClient()
