Pratik Mankawde a80cccb05a feat(telemetry): add Node Health verdict panel to Node Health dashboard ...

The dashboard showed 54 individual signals but no single answer to
"is this node healthy and doing its job?". A reader had to correlate
server state, ledger age and peer counts by eye.

Add a stat panel at the top that reduces the two conditions that define
a healthy observer node to one green/red verdict:

  server_state == 4 (Full)  AND  validated_ledger_age < 30s

Both terms use `== bool` so each yields 0/1, joined with
`* on(service_instance_id)` so the verdict is per node. Value mappings
render 1 as "Healthy" (green) and 0 as "Not Healthy" (red) with
background colouring, so the state is readable at a glance.

Placed at y=0 per the dashboard convention that gauges/stats lead;
existing panels shift down by 4 rows with no other change.

Verified live against Grafana Cloud: returns 1 for aws-dev-xrpl-1
(Full, validated seq 105,824,596).
