  NMS-20152: surface forecast failure conditions on the graph

runForecast only warned when the measurements response was empty, so a
response whose timestamps are present but whose Holt-Winters columns are
empty or all-NaN rendered a bare data line with three empty legend entries
and no explanation. Inspect the returned columns the way the legacy forecast
page does (via checkForecastWarning.js) and show a banner when: no HWFit
column is returned, the fit is all-NaN (including the multiplicative
Holt-Winters divide-by-zero when the metric reaches zero in-season), or the
confidence bounds have zero width. Restore the per-condition warnings table
in forecasting.adoc to match.
