Datacite and Bioschemas metadata by name doesn't cover single samples

[NRayya]

The functions for getting the metadata schema go like this :
public function modelSchemaByName(Request $request, $username, $projectName, $studyName = null, $datasetName = null)
Which requires a project name that is not available for single samples.
Entering the full names of user, project, study, dataset is not practical, usually results in errors especially wit h German names. Best to remove these functions and suffice with the using the id

• Remove from code
• update API platforms
