ILLDEV-451 state model selector

Pull request overview

Adds state-model selection support (ILLDEV-451) by introducing a selector on state models (currently keyed off ISO18626 serviceInfo.serviceType), persisting the chosen state model name on each patron request, and surfacing it through the broker API.

Changes:

• Add selector.serviceType to state model configuration and schemas; add selection logic in ActionMappingService.
• Persist state_model on patron_request (schema + migration) and thread it through create/update flows and API responses.
• Update/extend tests to include ServiceInfo.ServiceType and assert stateModel is set to returnables.
