Identify all actions the UI wants to perform (create, update, etc.)

List of all actions
* Get configuration for StudyManager
* Get all studies
* Get all patients of a study
* Get single patient via PatRef, root, and ext
* Get single patient via Sic (needed to check whether an SIC is duplicated) (does a separate endpoint make sense? Can be replaced by multi-patient validation)
* Get master data of a single patient
* Get encounters of a single patient
* Multi-patient validation (for batch creation)
* Creation of a single patient
* Batch creation of multiple patients (Rather as single endpoint instead of calling single creation endpoint iteratively -> helps with transaction consistency)
* Update of a single patient
* Deletion of a single patient
