[TASK] Replace hard-coded tt_content table in page layout partials

Since #102825 the table is available in the GridItem object. This can
now be used to replace the string "tt_content" with "{item.table}"
where possible. This way other record types can be rendered as grids
and will automatically function the same as content elements.
