RDF fixes

[jmillanacosta]

• Update backend function call to the new BDGraph where multiple {author:orcid} can be set for a generated RDF catalog

    def __init__(
        self,
        base_uri: str,
        version_iri: Optional[str] = None,
        title: Optional[str] = None,
        description: Optional[str] = None,
        # author: Optional[str] = None, ---> Not in use anymore
        # orcid: Optional[str] = None,  ---> Not in use anymore
        creators: Optional[List[Dict[str, str]]] = None,  # Use this

• Fix UI accordingly and document what each field means
• Implement custom prefixes for RDF graph
• ShEx are working well, but SHACL graph needs fixes:

biodatafuseui-2-backend-1  | 2026-02-03 10:10:12,516 - app.services.rdf_service - WARNING - ⚠️ SHACL generation failed: get_shacl_prefixes() missing 1 required positional argument: 'print_string_output

• Add custom namespaces for the SHACL/ShEx (currently it uses the default weso namespace from sheXer)
• Button to Select another visualization tool stops working after some step
• Explain better what the local/docker/docker bridge selection means and with which biodatafuseUI deployment type is each option applicable
