refactor(scenarios): split monolithic configuration into individual files

- Split `scenarios/scenarios.json` into individual JSON files under `scenarios/data/` named `<scenario-id>.json` - Split `scenarios/bundles.json` into individual JSON files under `scenarios/bundles/` named `<bundle-id>.json` - Updated `backend/server.js` to dynamically load scenario and bundle files from their respective directories - Updated documentation in `scenarios/SCHEMA.md` and `README.md` to reflect the new repository layout and contributor workflow Signed-off-by: Abhinav Sinha <[email protected]>
