Rename author_email→contact_interne, author_show_contact→contact_public across view/controllers/templates

- v_theses_full: author_email→contact_interne, author_show_contact→contact_public
- Updated schema.sql and live DB view
- Renamed all PHP variables: currentAuthorEmail→contactInterne, currentAuthorShowContact→contactPublic
- Restored contact_interne backoffice field with proper wiring (takes precedence over mail field)
- Updated admin/add.php, admin/edit.php, partage/index.php, public/tfe.php templates
