fix(rpc): use ResettingTimer for RPC duration metrics

Browse source 
The rpc/duration/all metric was using metrics.NewRegisteredTimer which
accumulates samples over the entire process lifetime. When exported to
Prometheus, quantile values grow to millions of seconds (displayed as years).

Switch to NewRegisteredResettingTimer which resets its sample buffer on
each Prometheus scrape, ensuring quantile calculations use recent data only.
