fix: GatewayClient robuste Response-Parsing + Isolierte Try/Catch

- ExtractToolData: unwraps content[0].text JSON + details
- GetStatusAsync: separates try/catch per step (ping, session, agents, queue)
- GetAgentsAsync: parses gateway agents[] array from sessions_list
- GetQueueAsync: extracts from cron response data.jobs
- gatewayOk no longer overridden by downstream tool errors
