[FIX] http_routing, portal: fix web translations not loaded

Reproduce the issue

    - Install eCommerce & Sales
    - Create a quotation
    - Preview
    - Switch to french on the website page
    - Click on "Signer & Payer"

    There is a lot of things not translated.

Cause

    On the website, the route `/website/translations` is called.
    The route calls a method `_get_translation_frontend_modules_domain`
    which teturn a domain to list the domain adding web-translations and
    dynamic resources that may be used frontend views.

    The missing translations are in the web module and the module is not
    loaded by the method.

This commit adds the `web` module to the domain and a missing
translation for the portal module
