Complete Frontend Prediction Workflow Orchestration

[Siddharthakhandelwal]

Evidence shows App.jsx prediction orchestration is truncated. The React application needs to reliably hit the predict API and send the results to the visualizing components.
Tasks/Acceptance Criteria:

• Complete the truncated handlePredict method in App.jsx.
• Parse the new JSON response schema correctly from /api/predict.
• Update frontend React state with the PDB object and metrics.
• Seamlessly pass the pdb prop to MolViewer to trigger rendering.
• Pipe the plddt measurements down to the metric visualization components.
