feat: add support for Codex's request_user_input tool

Implement full support for the request_user_input tool with both Web UI and CLI
components. This includes:

- New view and footer components for request_user_input tool UI
- Tool registration in knownTools and view registries
- Nested answer format support (Record<string, { answers: string[] }>)
- Backward compatibility with flat answer format (Record<string, string[]>)
- Permission handler updates for CLI request_user_input acceptance
- Type definitions and schema updates across shared/cli/server/web packages
- Translation strings for request_user_input UI elements
- Conditional footer rendering in ToolCard for question tools
