Add TypeScript types for parsers

**Description**
Currently auth lacks proper pagination support.

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

**Priority**: Low/Medium

The issue does not name any files, tests, or entry points, and its title conflicts with the body: the title requests TypeScript types for parsers while the description requests authentication pagination. First clarify which scope is intended and locate the relevant parser or auth entry point; done should mean the agreed change is implemented with tests and the requested defaults or types verified.
