[19.0][MIG] purchase_lot: Migration to 19.0

[apami0111]

Migrates purchase_lot from 18.0 to 19.0.

The models and views required no changes.
Tests were updated to reflect Odoo 19.0 API changes in stock models
and to remove dependencies on demo data.

@celm1990 Thank you for the feedback! I have squashed the administrative commits
and updated the code to use Command.create as suggested.

when using BaseCommon, there’s no need to create a res.partner record manually.

[BhaveshHeliconia]

Suggested change

cls.partner_id = cls.env["res.partner"].create({"name": "Test Supplier"})

[apami0111]

@BhaveshHeliconia Thank you for pointing that out! I have removed the manual res.partner
creation and replaced it with self.partner provided by BaseCommon.

Code review LGTM!

This product must be storable and tracked by lot. Instead of setting these fields below, please define them directly here.

Suggested change

	cls.large_cabinet = cls.env["product.product"].create(
	{
	"name": "Test Product Lot",
	"type": "consu",
	}
	)
	cls.large_cabinet = cls.env["product.product"].create(
	{
	"name": "Test Product Lot",
	"type": "consu",
	"is_storable": True,
	"tracking": "lot",
	"route_ids": [Command.link(buy_route.id), Command.link(mto_route.id)]
	}
	)

[celm1990]

Suggested change

	cls.large_cabinet.write(
	{
	"route_ids": [(4, buy_route.id, 0), (4, mto_route.id, 0)],
	"tracking": "lot",
	}
	)
