Gotify rejects a Grafana payload with 400 "Field 'message' is required", so a
translation step is mandatory. This adds a small standard-library Python
service: it accepts Grafana's JSON, builds a Gotify message, and posts it with an
app token.
Mapping:
firing -> priority 8, title "[FIRING] <alertname>"
resolved -> priority 3, title "[RESOLVED] <alertname>"
body -> the summary annotation plus severity, namespace, pod, instance, job
A multi-alert notification names the alert count instead of dropping the rest.
The script ships as a ConfigMap so no image build is needed. The app token comes
from a SOPS secret and belongs to Gotify application `grafana`.
