Add interventions and tickets lists to WebPortal (controllers, models, templates, i18n, setup)

[mapiolca]

Motivation

• Provide customers access to their interventions and tickets from the public WebPortal and allow administrators to enable/disable those list pages via configuration.
• Reuse WebPortal list infrastructure to display intervention and ticket records with appropriate columns, actions and localized labels.

Description

• Added localized language entries for interventions and tickets in website.lang for en_US, fr_FR, de_DE, es_ES, and it_IT.
• Introduced two new controllers FicheinterListController and TicketListController under htdocs/webportal/controllers/ and registered their routes in Context::initController via ficheinterlist and ticketlist definitions.
• Added two WebPortal model wrappers WebPortalFicheinter and WebPortalTicket under htdocs/webportal/class/ to expose limited field sets and status labels for lists.
• Extended FormListWebPortal (htdocs/webportal/class/html.formlistwebportal.class.php) to support intervention-related download_link/signature_link behavior and to render ticket consultation links and assigned-user display.
• Updated WebPortal templates list-titles.tpl.php, list-lines.tpl.php, and list-filters.tpl.php to include a consultation_link column when present.
• Added menu entries for interventions and tickets in htdocs/public/webportal/tpl/menu.tpl.php and new setup flags in htdocs/webportal/admin/setup.php to enable access via WEBPORTAL_FICHEINTER_LIST_ACCESS and WEBPORTAL_TICKET_LIST_ACCESS.

Testing

• No automated tests were executed as part of this change.
