Dashboards in Grafana; clean up after the Next.js app

Browse Source 
- k8s/grafana.yaml: Grafana 13.2.3 with a 1Gi PVC, sign-up and
  anonymous access off. The InfluxDB datasource (URL and token from the
  environment) and three dashboards — Live, Consumption, Charging — are
  provisioned from k8s/grafana/ via kustomize-generated ConfigMaps.
- server.yaml for the Go server (port 8080, UID 65532, smaller limits),
  image tag 2.0.0. The NetworkPolicy now admits Grafana to InfluxDB.
- ingress.yaml: IngressRoutes for car.stinnesbeck.com and Grafana
  (placeholder host car-grafana.stinnesbeck.com) with tls: {}, using
  Traefik's default certificate; the cert-manager Certificate is gone.
- secrets.example.yaml: drops the dashboard secrets, adds grafana-admin.
- AGENTS.md loses its Next.js block; SPECS.md describes the new setup.

The removal of web/ (the Next.js app) and of the stale .next/ cache
upstream had committed already landed in 51e6f6f, which was staged
together with the Go server by mistake.

Checked end to end in podman (Go server + InfluxDB 2.7.12 + Grafana
13.2.3): all 25 dashboard queries return the expected data, and the
dashboards were rendered with headless Chromium. Manifests validated
offline with kustomize and kubeconform. Nothing applied to a cluster.

# Kubernetes manifests — car.stinnesbeck.com
Plain manifests for the car server and its InfluxDB 2. They are only files: nothing here is
applied automatically. Apply them yourself.

## Before the first apply
1. **Check the ingress class** in `ingress.yaml`. It is set to `traefik-external` as a
placeholder; use the class of your public-facing Traefik.
1. **Check `ingress.yaml`:** the ingress class (placeholder `traefik-external` for the public
Traefik) and Grafana's host (placeholder `car-grafana.stinnesbeck.com`). Both hosts must be
covered by Traefik's default certificate.
2. **Create the Secrets.** Copy `secrets.example.yaml` outside the repository, replace every
`CHANGE-ME` (`openssl rand -hex 32` for tokens), then apply the copy:
`influxdb-auth` (InfluxDB admin password and token) and `mg4-server` (ingest token,
session secret, dashboard password, your ABRP API key and user token).
3. **Registry access.** If the `mg4-server` package on git.stinnesbeck.com is private, create
the `git-stinnesbeck-registry` pull secret (command in `secrets.example.yaml`); if it is
public, delete `imagePullSecrets` from `server.yaml`.
`CHANGE-ME` (`openssl rand -hex 32`), then apply the copy: `influxdb-auth`, `mg4-server`
(ingest token, your ABRP API key and user token) and `grafana-admin`.
3. **Registry access.** If the `mg4-server` package on git.stinnesbeck.com is private, create the
`git-stinnesbeck-registry` pull secret (command in `secrets.example.yaml`); if it is public,
delete `imagePullSecrets` from `server.yaml`.
## Apply
@@ -32,13 +34,12 @@ kubectl apply -f <your filled-in secrets file>
kubectl apply -k k8s/
```
The Let's Encrypt HTTP-01 challenge needs car.stinnesbeck.com to resolve to the public
Traefik before the certificate can be issued; check with `kubectl -n mg4 get certificate`.
## Notes
- InfluxDB's setup mode runs only on an empty volume. Changing `admin-token` in the Secret
later does not change the token inside InfluxDB.
- The server uses the InfluxDB admin token. A token scoped to the `mg4` bucket can replace it
later (`influx auth create --read-bucket … --write-bucket …`).
- InfluxDB's setup mode runs only on an empty volume. Changing `admin-token` in the Secret later
does not change the token inside InfluxDB.
- The server and Grafana use the InfluxDB admin token. A token scoped to the `mg4` bucket (read
for Grafana, read/write for the server) can replace it later.
- The dashboards are read-only in Grafana's UI. Change the JSON in `grafana/dashboards/`; the
ConfigMap name changes with its content, which rolls Grafana.
- To upgrade the server, push a new image tag and change `newTag` in `kustomization.yaml`.
