AI disclosure: This PR was primarily drafted with Codex using gpt-6.1-sol. I have reviewed and edited the final diff, and I am responsible for the content.

Summary

Human Input v2 contact-option search and batch responses omit effective IM provider information, so recipient cards cannot display a bound platform's icon. Add the required im_providers: list[IMProvider] field to both responses, using the existing batch lookup for current effective bindings and returning distinct providers or [] when unbound.

The projection preserves workspace override precedence and describes binding presence independently of Channel connection health. Editor permissions and recipient DSL remain unchanged; the response continues to omit binding IDs, identity details and management metadata. Generated TypeScript/Zod/oRPC contracts and the Console API reference are updated.

Fixes #45232

Validation:

• 271 focused backend controller, service, schema and OpenAPI-export tests passed.
• 6 frontend contact-provider tests passed.
• Scoped Ruff lint/format checks, backend Pyrefly, Contracts and Web type checks, and Vite+ formatting/lint checks passed.
• The full make lint && make type-check and vp staged commands were not run; the corresponding checklist item remains unchecked.

Screenshots

This change adds API response data; it does not change the rendered UI.

Before	After
Contact options omit IM provider information.	Contact options include im_providers: ["feishu"], or [] when unbound.
