refactor: streamline ApiService methods and enhance VlmRun node

- Simplified the createAgent and getAgentDetail methods in ApiService for better readability.
- Updated uploadUsingPresignedUrl to use a more descriptive method name, uploadToPresignedUrl.
- Added agentPrompt parameter to VlmRun node for improved agent execution options.
- Cleaned up code formatting for consistency and clarity.
