refactor: remove dead code (SentimentData, CircuitBreaker, TradeRow, unused configs)

- Remove SentimentData class and tests (superseded by SentimentAggregator)
- Remove CircuitBreaker, CircuitState, retry_with_backoff and tests (never used)
- Remove TradeRow ORM model and tests (no DB methods reference it)
- Remove unused config fields: circuit_breaker_*, selector_candidates_time, selector_filter_time
