Define and implement Latency SLOs (target: 95% of requests under X ms over a 28 day window) for the following gRPC methods:

• Relations.v1beta1.LookupSubjects
• Relations.v1beta1.LookupResources
• Relations.v1beta1.CreateTuples
• Relations.v1beta1.ReadTuples
• Relations.v1beta1.DeleteTuples
• Relations.v1beta1.ImportBulkTuples
• Relations.v1beta1.AcquireLock
• Relations.v1beta1.CheckForUpdate

The specific latency targets (X ms) need to be determined for each method based on historical data and performance requirements.

This ticket should encapsulate dashboards and app-interface SLO alerting for each endpoint.
