Add read-only support for LLMInferenceService

[LogicalGuy77]

Implements #175. The web application could already display InferenceService and InferenceGraph custom resources but had no visibility into LLMInferenceService, forcing anyone deploying a large language model to fall back to kubectl for basic questions such as whether the resource was accepted, how far the controller had progressed, and what topology and parallelism the specification actually requested. This change is scoped to reading; the create, edit and delete workflows are follow ups.
