C2(deploy-infra-alerting): impl fix ntfy payload template syntax

Browse source 
Use confirmed Grafana 12 template functions (coll.Dict, coll.Slice,
coll.Append, data.ToJSON) to build ntfy-native JSON payload.
Previous attempt hit 400 from ntfy — likely malformed output from
incorrect template syntax. This version uses the documented patterns
from Grafana's notification template reference.
