Update and enhance the existing web application found in the ui/ directory to support visualization of network traffic generated by the Leios prototype. This includes:

• Refactoring the app for compatibility with changes in the prototype's output and architecture
• Consuming live traces or logs emitted by ranking blocks, endorser blocks, votes, and certificates
• Providing clear, interactive views of protocol events and flows for both development and acceptance test scenarios
• Documenting the expected input format and usage for the visualizer

A usable visualization tool will make it significantly easier to inspect and demo the interactions within the Leios protocol, troubleshoot networking problems, and validate design assumptions in real time.

• Revive Leios visualization #622
• Visualizer: support live logs from Loki #652
