TLI 101.e -- Allow user to upload multiple models at once in Dashboard 2 and fix graph

[Jai0212]

Description:

Enable the functionality for uploading multiple models to Dashboard 2. The system should handle file validation, store models correctly, and display data and graphs for each uploaded model. Implement appropriate error handling for name and file type issues to prevent any unexpected failures or crashes. Also, add axes to the graph and display data when hovered.

A/C (Acceptance Criteria):

• Multiple Model Upload: Users should be able to upload multiple models instead of just one at a time in Dashboard 2.
• Error Handling: Implement error handling for the following scenarios:
  • Invalid file types (e.g., non-model files).
  • Duplicate model names.
• Dashboard 2 Output: Ensure Dashboard 2 produces the correct data and graphs for each uploaded model.
• Local Storage: Confirm that uploaded models are correctly stored in local storage without any issues.
• Hover Tooltip: Data is displayed when hovering over graph
• Axes: Axes are labeled in graphs of both dashboards
