Insights spotlight: news from folders 11 + 442, source editable in the menu

- Megamenu entries with the catalog or spotlight layout get two editor
  fields, "Data source folders" (source_pages) and "Data source
  categories" (source_categories); the extension stores them, the site
  package's listener reads them from the entry row.
- ProvideInsightsSpotlight reads its news from those folders (empty =
  11 + 442; the newer posts live in 442, the query only read 11) and,
  when set, only from those categories (Insights: Blog Post + Press
  Release). Newest datetime first, three cards.
- Pages carrying the menu are tagged with the news and event tables, so
  saving such a record refreshes the menu without a cache flush.
- VITEC field descriptions via a TCA override; spec v1.31, README.
