[UX] Web-based GUI Tool for Scenario Management

[Chulhee1Lee]

Description:
Currently, Pullpiri lacks any GUI tools, making it difficult for new users and non-CLI-savvy developers to manage scenarios, monitor services, or debug orchestration issues. A lightweight web dashboard would greatly improve usability and adoption.

Proposal:

• Web-based dashboard for scenario deployment, monitoring, and status visualization
• Real-time logs and metrics display
• Simple form-based scenario creation/editing
• Role-based access control integration
