Per WRITING-40913, rename the internalQueryExplainJoinCostComponents knob to internalEnableDetailedJoinExplain (wire name enableDetailedJoinExplain), since it will gate more than joinCostComponents. Make it settable via query settings (pqs_settable, FCV-gated) and read it through the query knob configuration so query settings overrides take effect.
