Add rate limiting for pagination

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

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

**Priority**: Low/Medium

Start by locating the pagination entry point in the utils code and identifying its callers. Determine how pagination configuration and defaults are represented, then clarify the expected rate-limiting behavior before implementing. Done means pagination is configurable, uses sensible defaults, and rate limiting is covered by relevant tests.
