PR Summary

Low Risk
Dashboard visualization-only change with no runtime, metrics, or consensus logic impact.

Overview
The Fee Target (USD per 1B L2 gas) panel in the SNIP-35 / Dynamic Gas Price dashboard row is switched from a time series to a stat visualization.

The Prometheus expression (snip35_fee_target_atto_usd / 1e9) and panel copy are unchanged; only the panel type is updated in get_panel_snip35_fee_target_atto_usd and the matching entry in dev_grafana.json.
