Update Service pages with all services

Currently, this is a first draft of a new serices page. https://hifis-review-app.hzdr.de/review-apps/hifis-hifis-net/114-services-page-needs-update/services

It works by putitng services pages into services/software, or cloud, backbone respectively, and then creates the boxes for those pages.

I would be happy to get a few early opinions:
