Add rate limiting for analytics

**Description**
Currently validation lacks proper sorting support.

**Proposed solution**
Add configurable sorting with sensible defaults.

**Priority**: Low/Medium

No files, tests, or entry points are named. First reconcile the title's analytics rate-limiting request with the description's validation-sorting request, then locate the relevant validation and analytics entry points; done should be defined by the confirmed scope, including configurable behavior and its expected defaults if sorting is the intended change.
