  NMS-20152: compute the forecast server-side via the measurements filters

The forecast is no longer computed in the browser. ForecastGraph now posts an
Outlier -> HoltWinters -> Trend -> Chomp filter chain to /measurements and
renders the server's HWFit/HWLwr/HWUpr/Trend columns, so the math is the
existing R-free HWForecast rather than a second hand-rolled implementation to
keep in sync. This makes Graph Start effective (the trailing Chomp cutoff),
uses the server's one-sided Outlier filter, and matches forecasting.adoc.

Adds a filter field to GraphMetricsPayload (FilterDef/FilterParamDef), deletes
the client-side statistics (forecasting.ts) and its unit tests, and updates the
component test to assert the posted filter chain. Trend color and the warnings
section in the docs are reconciled with the shipped behavior.
