## Summary
- `foldersFromFilesStructure` was `false` in Grafana's sidecar provider config, causing Grafana to ignore the subdirectory structure the sidecar creates from `grafana_folder` annotations
- All 18 TeslaMate dashboards were appearing in the root "Dashboards" folder despite having `grafana_folder: "TeslaMate"` annotations on their ConfigMaps
- Flipping to `true` makes Grafana replicate the sidecar's directory structure as UI folders
## Deployment and Testing
- [ ] Sync `grafana` app: `argocd app sync grafana`
- [ ] Verify TeslaMate dashboards appear under a "TeslaMate" folder in Grafana's dashboard list
- [ ] Verify other dashboards remain in the root "Dashboards" folder
