Enhance SkillTreeView with Asynchronous Initialization and Node Mapping

Browse Source 
This commit refactors the SkillTreeView class to include asynchronous initialization through FutureBuilder. The new version also replaces the integer-based node IDs with string-based IDs, aligning better with the SkillTreeNode model. The code now clears previous graph nodes and edges before adding new ones, preventing duplication. Additionally, the TreeNodeView component is now populated dynamically with data from the SkillTreeNode model, making the tree view more robust and integrated.
