Update models documentation

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

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

**Priority**: Low/Medium

Start by locating the controllers referenced in the description and compare them with the models documentation named in the title. Clarify the intended pagination behavior, configuration surface, and sensible defaults; the work is done when controllers support configurable pagination and the corresponding documentation is updated.
