insights: refactor- update insight view resolver to always preload series data
Created by: chwarwick
Previously the timeseries was loaded in the InsightViewResolver for JustInTime and Capture Group recorded series. Move the loading of the standard search timeseries data into InsightViewResolver for consistency.
Marked legacy insights query as deprecated and a todo to remove a resolver that should be removed when insights is removed.
Left in place the arguments supplied to points but noted in schema that they are not used and will be removed
resolves #33804 (closed) closes #27089 (closed)
