Improve Graph Interaction and Navigation with Iconify Icons and Enhanced Drag Handles

[navidshad]

📋 Summary

This PR enhances the graph interaction experience by replacing inline SVG icons with Iconify Tabler components in the GraphToolbar, implementing a space-to-pan navigation mode for smoother graph panning, and improving node interaction through the addition of drag handles and prevention of dragging on interactive elements. Additionally, cursor styling is simplified in the GraphChatPage by removing redundant overrides.

📝 Additional Details

• The use of Iconify Tabler components standardizes icon usage and improves maintainability.
• Space-to-pan mode allows users to pan the graph intuitively by holding the space key, enhancing navigation fluidity.
• Drag handles improve node manipulation, while non-draggable zones on interactive elements prevent unintended drag actions, improving UX.
