[16.0][IMP] shopfloor: multi company

[mt-software-de]

Make the shopfloor services work with the companies of the current menu, for the whole request.

This replaces the approach from #1133 (14.0) and its forward port #1142, following the review in #1133 (comment). Instead of overriding env on the base.shopfloor.process component, allowed_company_ids is now set once on the request env in the controller.

shopfloor_base

• New hook shopfloor.menu._get_allowed_companies(). It returns no companies by default, meaning no restriction.
• ShopfloorController overrides the new base_rest hook _get_collection_env_context(). It reads the menu from the SERVICE-CTX-MENU-ID header and sets allowed_company_ids to the menu's companies that the user belongs to. If the header is missing or invalid, the context is left untouched; the services still validate the header themselves.

shopfloor

• _get_allowed_companies() returns the companies of the menu's picking types.

Depends on:

• [16.0][IMP] base_rest: add hook to extend the request env context rest-framework#643

Supersedes #1142.
