(Simple) DOIP (Digital object interface protocol) server implementation

[timconrad]

Develop and deploy a DOIP server that provides the standard DOIP access interface for MaRDI research objects. The service must accept DOIP requests, resolve the referenced PID (MaRDI QID), and return metadata and components (e.g. fulltexts for publications). The initial scope includes support for the core DOIP v2 operations (hello, list-ops, retrieve) with all object bytes served from the existing storage backend (lakeFS for now).

The server uses the MaRDI FDO registry (#142 ) as the authoritative source of object manifests and components and runs within the MaRDI kubernetes cluster.

In a later stage, workflow invocation via DOIP will be introduced.

If a fair digital object has data as payload (e.g a FDO that is a Dataset and has data files), the DOIP server can serve this as a RO-Crate.

Changed the Dataset Template to have a showcase for this: https://portal.mardi4nfdi.de/wiki/Template:Dataset

For now, the RO-Crate option is only shown, if a Dataset has set P205, e.g: https://portal.mardi4nfdi.de/wiki/Dataset:6033087
