- TMWebDriver: add self.acks dict, HTTP implicit ACK on longpoll dequeue, WS explicit ACK handler, enhanced timeout diagnostics (4 cases)
- Fix: data.get('type') in 'result' -> == 'result'
- JS userscript: send ACK on script receive
- tgapp: fix proxy URL prefix
- mykey_template: add tg/proxy fields
