Python: Add Function Approval UI to DevUI (#1401)

* ensure function aproval is parsed correctly

* udpate ui, add deployment guide button, other debug panel fixes

* feat(devui): Implement lazy loading architecture with enhanced security and state management

Major architectural improvements to DevUI for better performance, security, and developer experience:

Performance & Architecture:
- Implement lazy loading for entity discovery - entities loaded on-demand instead of at startup
- Add hot reload capability for development workflow via new reload endpoint
- Reduce startup time and memory footprint by deferring module imports

Security Enhancements:
- Remove remote entity loading capabilities (POST /v1/entities/add, DELETE endpoints)
- DevUI now strictly local development tool - no remote code execution
- Add explicit security documentation and best practices in README

Frontend Improvements:
- Migrate to Zustand for centralized state management (replacing prop drilling)
- Add lightweight zero-dependency markdown renderer with code block copy support
- Improve gallery UX with setup instructions modal instead of direct URL loading
- Enhanced message UI with copy functionality and better token usage display

Testing & Quality:
- Expand test coverage for lazy loading, type detection, and cache invalidation
- Add comprehensive tests for new behaviors (+231 lines of test code)
- Improve type safety and documentation throughout

Breaking Changes:
- Remote entity loading via URLs is no longer supported
- Entities must be loaded from local filesystem only

* update ui issues, uupdate test descripion
