Sale Order Digitized Signature

This module adds a signature area to the sales order form so that a customer can sign directly on screen (for example on a tablet) when accepting a quotation or order.

• On the sales order form, a new "Customer Signature" field appears after the internal note area. It uses Odoo's signature widget, so the customer can draw their signature with a finger, stylus or mouse.
• The signature is saved as an attachment on the sales order, so it stays linked to that specific order.
• The printed sales order PDF report now shows a "Customer acceptance" section. If a signature was captured, the image of the signature is printed there; if no signature was captured, the section is simply left empty.

The module only touches the sales order model (sale.order) and the standard sales order form and report. It does not add new menus, buttons, automated emails, scheduled actions or validation rules. It is a simple, focused extension for keeping a visual proof of customer acceptance together with the order.
