Summary by CodeRabbit
WalkthroughThe REST API adds required task summaries to rack and tray responses. Flow defines task-summary protobuf fields, retrieves non-terminal tasks in deterministic order, enriches rack and component results, and serializes active task UUIDs in detail and list responses.

Move task-summary conversion to an API model receiver method.
NewAPITaskSummary performs protobuf conversion outside the API model receiver pattern. Add APITaskSummary.FromProto, initialize ActiveTaskIDs to an empty slice there, and call it from both parent model conversions.
rest-api/api/pkg/api/model/rack.go#L291-L291: Replace the helper call withar.TaskSummary.FromProto(...).rest-api/api/pkg/api/model/tray.go#L705-L705: Replace the helper call withat.TaskSummary.FromProto(...).
As per coding guidelines, “protobuf conversion should live on API model structs as ToProto and FromProto receiver functions.”

Move protobuf conversion onto APITaskSummary.
NewAPITaskSummary is a standalone protobuf conversion function. Implement func (s *APITaskSummary) FromProto(summary *flowv1.TaskSummary) and update rack and tray callers to invoke the receiver method. Preserve initialization of ActiveTaskIDs to an empty slice in that method.
As per path instructions, protobuf conversion should live on API model structs as ToProto and FromProto receiver functions.

Summary
taskSummary.activeTaskIdsto rack and tray detail/list responsesWaiting/Pending/Runningdefinition with existing active-only task queriesactiveTaskIdsis always present and empty when no task is active. Rack summaries include component-scoped tasks on the rack; tray summaries include only tasks that explicitly target the tray. Clients can derive the active count from the array length without introducing a second representation of the same state.Closes #5294
