Remove the "details" from the route (including refactor of everything details related)

[robbertbos]

Description

It is confusing that the "details" is in the route of the algorithm info page, but also on any of the other tabs. But at the same time the codebase is not neatly ordered, we could improve on giving everything with the tabs a single route and rename the everything related to it.

Technical stuff

• the details 'route' should be removed (so the systemcard itself shows details, url would be: /algorithm-system/id)
• the breadcrumb 'details' should be removed
• tabs should become part of the Navigation implementation, just like main, submenu and breadcrumbs are.
• also rename variables and filenames accordingly (to remove the everything details)
• consider how pages on filesystem should be grouped
