Subject: [PATCH] grafana: per-author hashrate window follows the dashboard
 range

New interval variable 'author window' (auto: about a quarter of the
range, never under 2 h; or pinned 1h..2d) replaces the fixed 6 h trailing
window in the hashrate-by-author panel, so a week view smooths and a
short view resolves.
