fix(charts): honour batch coverage on range-tab change

A range tab wider than the dashboard's batched series slice (90 / All on a
~30-day batch) re-read the narrow slice instead of fetching the requested
window, so the chart kept showing ~30 days. Thread the batch's coverage
day-span to the chart and read the preloaded slice only when the requested
window fits within it; a wider tab falls through to a real fetch. Also raise
the All-range request window past the old 365-day cap so longer histories
are no longer silently truncated client-side.
