Add TypeScript types for validation

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

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

**Priority**: Low/Medium

No files or tests are named. Start by locating the existing validation type definitions and sorting-related entry points, then determine how configurable sorting and its defaults should be represented. Done means validation types support sorting with sensible defaults and the relevant checks pass.
