This issue is automatically created based on existing pull request: #39452: Typecast incrementId variables always to a string

Description (*)

Ensure our calls to the sales_order table for the increment_id field are called with a string type and not an int type. When a module passed through an int variable, a full table scan occurs since the increment_id index can not be utilized.

Manual testing scenarios (*)

Create a small module and call the loadByIncrementId with an integer and see that this query is not hitting any index without this change.
