Integrate wave-based scaling system with WHOOSH server

- Add scaling system components to server initialization - Register scaling API and assignment broker routes - Start bootstrap pool manager in server lifecycle - Add graceful shutdown for scaling controller - Update API routing to use chi.Router instead of gorilla/mux - Fix Docker API compatibility issues - Configure health gates with placeholder URLs for KACHING and BACKBEAT 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
