Link to a partner in document pages

This module adds a Partner field to document pages in the Knowledge/Document Page app. On every page you can now pick a partner from your contacts, and that link is stored on the page itself.

Where it appears: - On the document page form, the Partner field is shown right after the parent page field. - In the list of document pages, the Partner column is also displayed. - In the search/filter area of the document page list, you can filter by Partner and group pages by Partner.

Business behaviour: - The link is a simple reference to a contact; no automatic emails, checks or computations are added by the code. - Because the field is indexed, filtering and grouping by partner are fast even with many pages.

What it touches: - It extends the document.page model with a partner_id field pointing to res.partner. - It only changes the existing document page form, list and search views; no new menus or reports are created.

This is useful when you keep notes, procedures or documentation per customer or supplier and want to retrieve all pages related to one partner in a single click.
