Move AddedWho config to RecActionOptions and refactor usage

Centralize AddedWho under RecAction in appsettings.json and add it to RecActionOptions. Update InvokeRecActionViewCommandHandler to use IOptions<RecActionOptions> for strongly-typed configuration access, replacing previous config-based retrieval. Removes global AddedWho property for improved maintainability.
