Personal information page for contacts

This module does not add any new fields, menus or business rules by itself. Its only effect is a small change on the standard contact form.

• On the contact form (the res.partner screen), a new tab called "Personal Information" is added after the existing "Internal Notes" tab.
• This tab is hidden when the contact is a company; it only appears for contacts that are persons.
• The tab is currently empty: it contains a placeholder group with no fields inside.

Because the page is empty, users will not see any new data to fill in after installing this module alone. Its purpose is to provide a common, standard place where other add-on modules can add their own personal information fields (for example, birth date or other personal details) without each module creating its own tab.

No new models, no automated computations, no checks, no emails and no scheduled actions are introduced. The module only touches the contact form view and depends on the base module.
