Default layouts and archive browser

Instead of generating a default layout, we create one layout item that shows and allows to edit all quantities and subsections of the section that represented by the current route.

• this is used as the only and root item for the default layout on the entry overview
• entry sections use the layout system as well and will use this as the only and root item

Things todo:

• create components that show/edit all sub sections and quantities
• add the archive data of the current route to the archive in useArchive (depends on #66 (closed))
• create the "Section" layout item
• use the layout system in EntrySection similar to its use in EntryOverview
• use as default layout for EntryOverview is there is no schema defined layout
