[BUGFIX] Correct field name casing for subTitle and navTitle in TypoScript queryFields

The Solr schema defines subTitle and navTitle as camelCase field names, but the TypoScript configuration referenced them as subtitle and navtitle (all lowercase). Since Solr field names are case-sensitive, both fields were indexed correctly but silently excluded from all search queries.

Fixes: #4617
Ports: #4618
