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]>

Dropping ALL capabilities and adding back only what is explicitly needed follows the principle of least privilege and is a CKS exam requirement.\n\n**Your task:**\n\nCreate a Pod named `nocaps-pod` using `nginx:alpine` with the following capability configuration in the container `securityContext`:\n- Drop **ALL** capabilities\n- Add back only **`NET_BIND_SERVICE`** (required by nginx to bind to port 80)\n\n```bash\n# Verify:\nkubectl get pod nocaps-pod -o jsonpath='{.spec.containers[0].securityContext.capabilities}'\n```",
