Sale Payment Management

This module lets salespeople handle customer payments directly from the Sales app. A new Payments menu appears under Sales, opening a list of payments already filtered to incoming customer payments, so users can create and view them without going through Accounting.

On customer invoices, the Register Payment button is made available to sales users, so they can record a payment straight from the invoice. When a salesperson who is not in the Invoicing group opens a payment form, the Partner Type field only offers Customer, preventing them from recording vendor payments by mistake.

Visibility is controlled by sales role: - Sales users who only see their own documents can only view payments they created themselves. - Sales users who see all documents and sales managers can view all customer payments. - Accounting/Invoicing users keep full access to all payments.

Sales users can create payments but cannot modify or delete them, and they can read payment methods. The module touches account.payment, account.move and account.payment.method.
