fix: wrap executeActionsWithLoop in try/catch to prevent raw 500 errors

When the AI Gateway returns a non-200 (e.g. tool validation failure),
callWebhook throws an unhandled Error that bubbled up to Slim as a raw
500 page. Now caught gracefully with a Hebrew error message returned
to the user instead of "Slim Application Error".
