refactor!: simplify runtime coordination #7

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.
