Extend Subscription Detail Page for Customer View

Description: Extend the subscription detail page for the customer view (page: /company-subscriptions-detail/{appid}) to display more detailed information about the app, similar to the app detail page on the app marketplace. This includes adding images, language tags, documents, and privacy information. Additionally, ensure that the technical user details are still highlighted, and add a use case chipcard inside the subscription box.

Details:

1. Enhance App Information Section

Similar like on the app details view (documented here https://portal.int.catena-x.net/documentation/?path=user%2F04.+App%28s%29%2F01.+Marketplace%2F02.+App+Details.md) fetch from the api endpoint additional details (see list below) and display them inside the detail page.

Endpoint: /api/apps/{appId}

App images ("images" property; take the image ID and fetch the respective image via the document endpoint - api slice should be already fully existing, just to be reused here)
App language ("languages" property)
App documents ("documents" property)
App privacy information ("privacyPolicies" property)

2. Technical User Details

Ensure that the technical user available on the page bottom is a hyperlink if the user has the permission view_tech_user_management. Users with the permission are able to see the hyperlink and to click on the hyperlink to directly access the technical user detail page and to lookup all the technical user details.

3. Responsiveness

Ensure that the page is fully responsive for full display screen, half screen as well as mobile version
