Add TypeScript types for controllers

**Description**
Currently middleware lacks proper analytics support.

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

**Priority**: Low/Medium

The title asks for TypeScript types for controllers, while the description asks for configurable middleware analytics, so first reconcile which change is intended. Locate the controller and middleware entry points, then confirm the expected configurable options and defaults. Done should mean the agreed scope is implemented and its behavior or types are covered by the repository's existing checks.
