fix: remove field precision in Sales and Purchase Order for percentage fields (backport #44376)

[mergify]

Remove field precision for Sales Order and Purchase Order fields:

• % Delivered
• % Amount Billed
• % Picked
• % Received

This is to maintain consistency as precision is not used while setting Status on backend.
