CRM Partner Required

This module changes how CRM opportunities are captured in Odoo. It makes the customer field (partner_id) required whenever the record is an opportunity, so an opportunity cannot be saved without a customer linked to it.

Where it applies: - The main opportunity form: the customer field is marked as required when the record type is an opportunity. - The quick create form used to create an opportunity on the fly: the customer field is also required there.

Business rule added: the requirement is conditional. It only applies when the record type is 'opportunity'. Plain leads (not yet converted into opportunities) are not affected, so users can still register leads without a customer and qualify them later.

What users see: if they try to save or quick-create an opportunity without choosing a customer, Odoo blocks the action and asks them to fill in the customer field.

Areas touched: the CRM lead/opportunity model (crm.lead) and its forms. No new menus, reports, emails, scheduled jobs or automatic computations are added; the module only enforces the mandatory customer field on opportunities.
