Add TypeScript types for services

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

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

**Priority**: Low/Medium

Start by locating the controllers and services referenced in the issue, then inspect how responses currently handle collections and whether any pagination exists. Add configurable pagination with sensible defaults and verify that controller results expose the expected paginated behavior; the issue does not name specific files or tests.
