fix: clean up dimension mapping graphs

[tpluscode]

Dimension mappings are stored as instances of prov:KeyEntityPair similar to

[
  rdf:type prov:KeyEntityPair ;
  prov:pairKey "164" ;
  prov:pairEntity <https://ld.admin.ch/dimension/term> ;
] .

<https://ld.admin.ch/dimension/term> a prov:Entity .

When such a pair was removed, the a prov:Entity triple was left over. It does not have any side effects but is clutter nonetheless. This PR ensures that they will be removed when a dimension mapping is saved.

Additioanally the query below can be used to clean up any dangling triples from mapping graphs.

PREFIX prov: <http://www.w3.org/ns/prov#>
PREFIX csvw: <http://www.w3.org/ns/csvw#>
PREFIX cube: <https://cube.link/>

DELETE {
    graph ?mapping {
        ?entity a prov:Entity .
    }
}
where {
    graph ?mapping {
        ?mapping a prov:Dictionary .
        ?entity a prov:Entity .

        filter not exists {
            ?pair prov:pairEntity ?entity .
        }
    }
}
