feat(infospace): evaluate 3 missing WoN entities (C.1)

Fills the 988 entity / 985 evaluation gap in the Wealth of Nations
infospace. Entities advanced_state_of_society, bank_notes, and
bank_systemic_risk_management had no evaluation files; runs through
Gemini (2.5-flash / 2.5-flash-lite for the last one, which hit the
free-tier RPM limit) bring the eval count to 988.

per_entity_mean nudged from 3.955635 to 3.95668; viability still
6/6 PASS.
