Add copy button to graph error panels for LLM debugging

[e-gineer]

Summary

Adds a copy-to-clipboard button to graph error displays to make it easy for users to copy error information for debugging with LLMs.

Features

• Minimal UI: Just copy icon in top-right corner, no header text
• Tooltip: "Copy to clipboard" on hover
• Markdown Format: Optimized for LLM consumption
• Rich Metadata: Includes panel name, type, status, and timestamp
• Comprehensive Context:
  • NODE_AND_EDGE format: Complete status summary + detailed per-node/edge errors
  • Legacy format: Panel-level error with metadata
• Visual Feedback: Icon changes to filled + green for 1 second on success
