Add method to create missing EKÁER history records

Introduced CreateMissingEkaerHistories in FruitBankDataController to generate Pending EKÁER records for inbound shipping documents and completed outbound orders lacking such records from a specified date. The method is user-invoked, idempotent, logs actions and errors, and supports SignalR notifications.
