Create FE component for error handling

[epintozzi]

This component should be the standard used for displaying any errors received from the BE to the FE when trying to create, update, or delete resources.

Rough mockup - open to suggestions/changes

The plan is to implement the following changes/additions:

• ErrorContext.tsx file to pull any errors on the backend that are handled with the error_serializer.
• in App.tsx wrap routes with ErrorProvider so that all components have access
• In the apiCalls.tsx, ensure that errors go to ErrorContext so that users can see them.
• Write a handler function to pass errors to ErrorContext and also console log errors in the console for devs.
• update all fetch functions to use the new handler function
• Test the functionality in the companies component to ensure that its working as expected.
• Write cypress tests, if needed.
