Pratik Mankawde e103bd32f6 fix(telemetry): flush spanmetrics every 15s so Cloud rate panels render ...

Span-derived metrics (span_calls_total, span_duration_milliseconds_*) were
emitted at the spanmetrics connector default of 60s. Grafana Cloud stores one
datapoint per flush, but dashboard panels use rate(...[$__rate_interval]),
whose window at short ranges (<=1h) falls below 60s — leaving <2 samples per
window, so those panels rendered "No data" on the Cloud datasource. (Local
Prometheus scrapes at 15s, so local dashboards were unaffected.)

Set metrics_flush_interval: 15s so every rate window holds >=2 samples at any
dashboard range. Trade-off: ~4x span-metric datapoints pushed to Cloud. Native
insight metrics (ledgermaster_*, jobq_*, peer_quality) already push faster and
were never affected.
