Pratik Mankawde 628882f686 fix(telemetry): replace the alert notification body with the rule's own prose ...

Grafana's default notification body appends every expression node's value and
every label, so an alert arrived as `Value: A=0, B=0, C=1` over a five-line
`key = value` dump. The refIds mean nothing to a reader and the labels repeat
the title.

Add templates.yaml and point both Slack receivers and the email receiver at it,
so the body is the rule's own description plus its remediation line, and any
panel_* annotation renders as a link.

Rewrite all 13 descriptions to be status-neutral, since the same annotation is
rendered when the alert resolves: a firing-only wording made a resolved
notification claim the node had stopped closing ledgers while reporting a
healthy rate. The reason to care moves to a new `action` annotation, which the
template prints only while firing. Each description now formats its value with
printf and states its threshold, rather than emitting a bare float.

Also fix the Slack title, which referenced a `rulename` label that no rule sets
and so rendered blank; `alertname` is the label Grafana always provides.
