Receipts Print and Send

This module makes it possible to email receipts directly from Odoo. On a receipt document (a customer receipt or a vendor receipt) that is already posted, a highlighted "Send" button appears in the form header, next to the usual invoice send button. Clicking it opens the standard send-by-email flow, but the message is prepared with a receipt-specific email template instead of the normal invoice template.

The new template is called "Receipt: Send by email". It is addressed to the document's customer or vendor, uses the salesperson's email address when available, and puts the receipt PDF in attachment. The subject line shows the company name and the receipt reference. The body greets the contact (including the parent company name when relevant), states the receipt number, any origin reference and the total amount, and then adapts: if the receipt is already paid or in payment it says so, otherwise it politely asks for payment and, when available, shows the payment communication and the bank account number. A signature from the responsible user is added if one is set.

The module only touches the accounting documents model account.move and the existing invoice form view; it does not add new menus or reports of its own.
