Display basic node information with copy-to-clipboard

[ChristianHuehn]

Feature request

Part of Epic #136

Description

As a visualization user, I want to see basic node information (name, type, file path) in the slide-in panel with a copy-to-clipboard button for the path so that I can quickly access and share node details.

Acceptance criteria

• Panel displays node name prominently
• Node type is displayed (e.g., class, module, package)
• Full file path is displayed
• Copy-to-clipboard button appears next to the file path
• Clicking copy button copies the path to clipboard
• Visual feedback when path is copied (e.g., tooltip, icon change)
• Handles nodes with missing or incomplete information gracefully

Assumptions & Exclusions

• Only the file path has copy functionality (not name or type)
• Basic clipboard API usage (no fallback for older browsers initially)
• Path displayed as-is (no truncation or formatting)

Development notes (optional Task Breakdown)

• Create UI layout for basic information section
• Bind node name, type, and path to template
• Implement copy-to-clipboard functionality
• Add visual feedback for successful copy
• Handle edge cases (missing data, empty paths)
• Style the information display section

None - requirements are clear.
