Sync Connection

post/v1/graphs/{graph_id}/connections/{connection_id}/sync

QuickBooks: fetches transactions, balances, and chart of accounts. Mercury: pulls the bank feed (a 60-day window by default, or from since_date / the full backfill on full_rebuild) and captures it into the inbox. Plaid: continues from the Item's stored cursor (added, modified and removed transactions), or replays its history on full_rebuild / since_date. For all three the envelope is pending with the run's task_id, and completion is reflected in the connection's last_sync timestamp and last_sync_result. External connections are push-based and have nothing to pull; the envelope is completed with a null task_id and a message saying so — there is nothing to poll. Returns an OperationEnvelope; supports Idempotency-Key.
