Extend Solr search: content coverage, 14.0.2, news recency, result images

- Index the text columns of the market/solution Content Blocks and the
  vitec_items/vitec_faq_items collection children; story documents now
  include their body (inline tt_content children via
  tx_vitec_usecase_content, same per-element extraction as pages) -
  stories were indexed with subtitle and teaser only until now
- Upgrade EXT:solr 14.0.0-RC1 -> 14.0.2 final (the Solr image moved to a
  fresh volume because the configset changed; synonyms restored via REST)
- News decay with age by publication date: crdate is the import date, so
  news map datetime to created; boost function gated to news only
- Results carry `image`: processed 640px tile image per type,
  root-relative, null for pages and downloads
- Spec v1.21: 7.16 states the /_json prefix and lists `solution` in the
  type vocabulary; footer had been stuck at v1.19
- suggest-demo.html fetches through /_json after the URL swap
