JSON Validation window

[hunterhector]

Is your feature request related to a problem? Please describe.

This project uses JSON in several key places, including:

1. The data files (data packs)
2. The ontology file
3. The configurations

Currently, these files are directly uploaded or edited via simple text boxes. No validations are performed. This will introduce bugs in a later process.

Describe the solution you'd like Introduce a general JSON input, visualization, and validation box, which can take a schema as an argument. Some tools like this may be good: https://www.npmjs.com/package/jsoneditor-react

Describe alternatives you've considered A clear and concise description of any alternative solutions or features you've considered.

Additional context Add any other context or screenshots about the feature request here.
