fix: Add Helper for Field Processing & Update Code Validation Logic (l…

…angflow-ai#4429)

* 📝 (GenericNode/index.tsx): Add import statement for cloneDeep from lodash library
📝 (GenericNode/index.tsx): Add import statement for processNodeAdvancedFields helper function
📝 (GenericNode/index.tsx): Add edges variable to store edges state using useFlowStore hook
📝 (GenericNode/index.tsx): Modify onSuccess callback to process and update node data with advanced fields using processNodeAdvancedFields helper function

* ✨ (process-node-advanced-fields.ts): add a new function to process advanced fields of a node based on edges in a graph for better customization and control.

* ♻️ (GenericNode/index.tsx): Remove unused import of cloneDeep from lodash to clean up the code and improve maintainability.

* 🔧 (process-node-advanced-fields.ts): rename variable edgesWithNode to relevantEdges for clarity and consistency
🐛 (process-node-advanced-fields.ts): fix condition to check relevantEdges length instead of edgesWithNode length for correct logic
