Update menu generator to better display existing schema IFC-834

[dgarros]

fixes ifc-834

This PR improve the compatibility for the current schema format with the new menu. By default, if a node/generic is meant to the included in the schema it will be displayed at the top level.
Menu placement can still be used as well. In order to support the current format, the identifier for the schema is no longer using a :, instead the identifier is identical as the element of the schema <namespace><name>.

if a menu item with the same identifier already exist in the menu it will take precedence over what is in the schema.

This PR also adds the initial support for permissions to the menu.
For each CoreMenuItem it's now possible to defined a list of required_permissions, currently only global permissions are supported.
At least of the permission must match for the menu to be visible.
By default, the menu Admin will be only visible if the user has the global:super_admin permission

And finally, the structure of the menu has slightly changed

• Credential is now under Unified Storage
• Webhook is now part of a new Integrations menu item

Aside my minor comment this looks good to me. However it doesn't seem to work, it looks like the frontend isn't sending in an authorization header for the menu api:

This part should never come into play get_menu() will always send an object but it might be an unauthenticated object. Even if that happens I think it could make sense to run the code below so that we'd also hide the admin menu for anonymous users. The function signature here could change account: AccountSession | None = None -> account: AccountSession
