The read-only token for Grafana needed a manual influx command and a
Secret. InfluxDB generates every token but the admin one and ignores a
chosen value (tested on 2.7.12), so it cannot be preset in a Secret.
Instead an init container in the Grafana pod creates it at every start
with the admin token, deletes the one from the previous start, and
writes only the read-only token to a memory-backed volume; the
provisioned datasource reads it with $__file{/run/influx/token}. The
Grafana process never sees the admin token. The grafana-influx Secret
is gone from the template and the README.
Tested in podman: InfluxDB 2.7.12, the script run twice as the Grafana
user (the old token is replaced, not piled up), and Grafana 13.2.3
reporting the datasource healthy with the file-based token.
