[FIX] construction_developer: mark uom of WI required if no product

[assh-odoo]

Currently, an error occurs when a user creates a work item.

Steps to Reproduce:

• Install the construction_developer.
• Go to Sales > Products > Work Items.
• Create a new record by entering only the name and save.

Error:

ValueError: ValueError('NotNullViolation(\'null value in column "uom_id" of relation "product_template" violates not-null constraint\\n
DETAIL:  Failing row contains (83, 1, null, null, null, null, 2, 2, service, no, null, {"en_US": "sadsa"}, null, null, null, null, 0.0, null, null, f, t, t, t, null, null, null, 2026-03-17 06:18:40.850849, 2026-03-17 06:18:40.850849, null, null, 15, null, {"1": 2}, null, null, null, null, null, null, purchase, null, null, null, manual, no, order, null, null, null, null, null, null, null, 0.9).\\n\')

'record.x_unit_cost'

This error occurs because when a product is not set on the work item, a new product
is created using the work item name. During this process, the system tries to assign
uom_id from x_unit_custom_id 1, which is empty if the user has not selected any unit,
causing the error.

This commit ensures that the field x_unit_custom_id is set as required
at the view level.
