Subject: Issue with Creating a New Blanket Order in sale_blanket_order_revision
HT00967

Description of the Issue:
An error occurs that prevents the creation of a new Blanket Order. The following error message is displayed:

"Order Reference and revision must be unique per Company."

Steps to Reproduce:

Launch Runboat (with a clean instance without any additional modules).
Install the sale_blanket_order_revision module.
Attempt to create a new Blanket Order.

Observations and Evidence:

The issue appears to be related to the uniqueness check when saving the Blanket Order. The system attempts to validate the reference while the Blanket Order still has a "Draft" name.
If additional modules are installed (see evidence below), the issue does not occur.

Evidences:
Error Message While Saving Blanket Order:

If Enable to create a sequence number on draft state::

Successful operation after additional modules are installed:

So the problem shoud be on checking made in the save moment, that the Blanket Order will be with "Draft" name.
