The Aggregated ingest tier bucketed trades by hour incl. the current, still-growing
hour, then upserted via ON DUPLICATE KEY UPDATE (mutable rows). The PnL engine
checkpoints positions by row Id, so a bucket that keeps growing after being applied
had its later growth silently skipped (Id <= LastAppliedTradeId).
Extract the duplicated aggregation logic from PollingWorker + TradeHistoryWorker into
TradeAggregation.AggregateCompletedHours, which only aggregates COMPLETED hours; the
current hour is deferred (re-fetched next cycle) so every persisted aggregate is
immutable. +3 unit tests.
