Partner and customer records are easier to manage, with clearer choices between companies and individuals and simplified address handling for contacts. The update also streamlines related account, VAT, payment, CRM, delivery, event, HR, repair, and point-of-sale views so users can access key information through cleaner forms and counters.

Add a new selection field company_type, replacing is_company. To keep
backward compatibility, the old field is still stored and considered
as an interface field for the new company_type field. The deprecated
tag is added to ensure people will udpate their module.

The customer form has been redesigned to make it clearer whether a record is a company, individual, contact, or address. Contact lists, kanban cards, customer menus, and related accounting and CRM views were adjusted so users can manage customer information with less confusion.
