Add unit tests for hooks

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

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

**Priority**: Low/Medium

First clarify whether the goal is unit tests for hooks or configurable pagination, since the title and description conflict. Then locate the store and hook entry points, identify the expected pagination defaults, and add tests that show the configured behavior is complete.
