make record editor dynamic based on URL type

[drjova]

Currently, the record editor for the backoffice only supports the "authors" type, as seen in the example https://github.com/inspirehep/inspirehep/blob/681c501b7083edc00dc99cd5092acdeac700141c/record-editor/src/app/core/services/backoffice-api.service.ts#L110-L111

To improve flexibility, the record editor should be updated to handle various record types dynamically, similar to how the record and holdingpen editors operate. This can be achieved by utilizing the URL structure to identify the type dynamically. For instance, the editor endpoint could be formatted as follows:

editor/workflows/<type>/<uuid>

Acceptance Criteria:

Modify the record editor to accept and handle different parameters based on the URL structure.
Ensure support for multiple record types (e.g., authors, publications, etc.).
Maintain or improve existing tests to cover dynamic URL-based record type handling.
Ensure no regression for the existing "authors" type.

Additional Notes:

Review the existing logic in the record and holdingpen editors for guidance on implementing dynamic type handling.
