Simplify InvokeRecActionsCommandHandler dependencies and logic

Refactored InvokeRecActionsCommandHandler to only require ISender,
removing IServiceScopeFactory, IHttpClientFactory, and ILogger.
Replaced concurrent invocation and error handling with a simple
sequential loop, streamlining batch recommendation action execution.
