(Migrated from gitlab.com)

/cg/orderbook and /cmc/orderbook/{market_pair} run the same LCD fanout (orderbook_sim::simulate_orderbook_cached → resolve_fee_bps + build_orderbook_data) as the native limit-book endpoints, but were registered on api_router under only the general per-IP governor. This moves both into lcd_heavy_router so they inherit the stricter rate_limit_lcd_heavy_rps throttle.

Scoped to the orderbook routes per the issue triage ("Move both routes to the lcd_heavy_router"). The cg/cmc tickers/summary N+1 fanout is tracked separately in #288.

cargo check clean.
