Refact: Enhance Property editing UI for KG Nodes

Overview

This PR fixes multiple issues in the graph visualization UI related to property editing, particularly for entity_id and entity_type updates.

Changes

1. Fix Entity Type Update Handling (79a17c3)

Problem: When updating entity_type property, the graph wasn't using the correct value.

Solution:

• Use finalValue for none entity_id changes to ensure the new ID is properly applied
• Maintain original value behavior for other property types
• Fix property update logic in the graph store

2. Change Node Color According to New Entity Type

Problem: When entity_type was changed, node colors and legend weren't updating in real-time.

Solution:

• Extracted color constants and logic to a dedicated utils/graphColor.ts module
• Implemented resolveNodeColor function for consistent color resolution
• Added automatic node color updates when entity_type changes
• Updated legend to synchronize with type changes
• Refactored and simplified color logic in useLightragGraph hook (reduced from 219 lines to more maintainable code)

3. Property Edit Dialog Optimization

Problem: Input values weren't consistently trimmed in the property edit dialog.

Solution:

• Ensure trimmed values are used consistently throughout the edit dialog
• Improve input value normalization

Testing Checklist

• Entity ID updates apply correctly in the graph
• Node colors update immediately when entity_type changes
• Legend updates to reflect new entity_type values
• Property edit dialog properly trims input values
• No regression in other property editing functionality
