fix: resolve circular dependency between utils and service libraries

Moved useAuthStore from utils to service to break circular dependency:
- utils was importing from service (supabase client, types)
- service was importing from utils (useAuthStore)
- Solution: moved useAuthStore and related storage utilities to service

Changes:
- Created libs/service/src/storage/ with cookies.ts and local-storage.ts
- Moved use-auth-store.ts from utils/hooks to service/hooks/auth
- Updated all 20+ files to import useAuthStore from service instead of utils
- Removed useAuthStore export from utils
- Added storage exports to service index

This fixes the build error: "Could not execute command because the task graph has a circular dependency"
