[ADD] sign_stamp: add custom Stamp field in Sign app

Implemented a new 'stamp' sign item that displays company logo and details
(name, address, city, country, VAT).
External users can upload a logo and edit details via a custom dialog. Stamp is saved and rendered properly during signing and in the final PDF. Includes fallback for missing logo and handles user input cleanly.
