JSON Validation window

**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**

The issue identifies data packs, the ontology file, and configuration inputs but names no files or tests. Start by locating the three JSON upload or editing paths and reviewing their current text-box handling; done means a shared schema-aware input provides visualization and validation across all three paths.
