Portal Accounting Personal Data Only

When this module is installed, portal users (customers or suppliers who log into the portal) can only see the accounting documents that belong to them personally. Odoo's standard behaviour lets a portal user see all invoices where any member of their organization is a follower, which can leak private documents between colleagues or departments. This module disables those standard portal rules and activates two stricter ones.

• The first rule limits which invoices (accounting entries, account_move) a portal user can read: only those where the user's own contact is among the followers of the document.
• The second rule applies the same restriction to the individual invoice lines (account_move_line), so lines belonging to other people's invoices are hidden too.

Both rules apply only to the portal user group, so internal users are unaffected. The change is automatic at installation: the original Odoo portal rules are archived (deactivated), and if the module is later uninstalled, those original rules are restored. There are no new menus, buttons, reports or scheduled actions; the module only changes what portal users are allowed to see in the accounting area.
