Get ServicePrincipal by ID

Represents a non-human identity used for system integrations and automated processes within Benchling. Service principals act as the identity for service accounts that perform actions via APIs or background processes without human intervention. Unlike User, which represents a human user, ServicePrincipal is used when an integration or automated system needs to be attributed as the actor for auditing and attribution purposes. Service principals implement the Principal interface, allowing them to appear as creators or actors on domain objects. Also known as "service account" in some contexts.
