Odoo Checkout Form Cleanup

When a customer presses “Checkout” on my Odoo website I want the address form to show only the essentials—Name, Address, Phone number and Email. Please remove the VAT box and the Company Name box entirely and keep the page layout tidy so nothing looks blank or mis-aligned once those two fields disappear.

No new fields are needed and the change should apply to every checkout flow, whether the shopper is logged in or checking out as a guest. Validation, translations and mobile responsiveness must keep working exactly as they do now.

Deliverable: an updated module or safe view override that I can install on staging first, along with a brief note of what files you touched so I can trace the change later.
