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]>

Create a ConfigMap named `app-env` with two keys:\n   - `LOG_LEVEL=debug`\n   - `APP_PORT=8080`\n\n2. Create a Pod named `env-pod` using `busybox:1.36` with command `sleep 3600` that loads **all keys** from `app-env` as environment variables using `envFrom`.\n\n**Verify:**\n```bash\nkubectl exec env-pod -- env | grep -E 'LOG_LEVEL|APP_PORT'\n```",
