Keep financial ownership, atomic publication and refresh CAS. Failed refresh leaves cookies untouched; logout still clears them. Remove full-history candle prefetch and special metadata retries. Use native Pino request context instead of parallel middleware. BREAKING CHANGE: remove investment stateVersion, queued sync state, and tbank-sync status progress/resources. Consumers must observe resources through sync=observe with the updated frontend contract.
