Refactor types for better readability

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

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

**Priority**: Low/Medium

Start by locating the controllers mentioned in the issue and reading how requests currently flow through them. Determine where retry behavior and configuration belong, then verify that sensible defaults and configurable retries work across the affected controller paths. The issue does not name files, tests, or an entry point, so repository exploration is required.
