Module cache 

Cache layer — Phase 1: a thin Station-level wrapper around digdigdig3::core::rest_cache::RestCache keyed by (ExchangeId, AccountType, raw_symbol) for get_ticker.

Step 6+: extend with orderbook L1 TTL, symbol metadata, and warm-start from disk. See docs/plans/station-architecture.md §6.
