Improve timeout resilience for Telegram and n8n integrations.

Add configurable Telethon retry/connect settings, enable retry-on-fail for external n8n nodes, and document recovery steps for Telegram and workflow activation timeouts. Co-authored-by: Cursor <cursoragent@cursor.com>

+Если в логах `Connection to Telegram failed ... TimeoutError`:
+
+1. Проверь доступность Telegram с хоста (фаервол/провайдер/блокировки).
+2. Оставь `TG_USE_IPV6=false` в `.env`.
+3. Подними таймаут/ретраи, например:
+   - `TG_CONNECT_TIMEOUT=30`
+   - `TG_CONNECTION_RETRIES=30`
+   - `TG_RECONNECT_WAIT=20`

+Если в `n8n` при активации workflow ошибка:
+`The connection timed out, consider setting the 'Retry on Fail' option`
+
+1. Открой в workflow узлы:
+   - `Telegram Trigger`
+   - `Qdrant Insert`
+   - `Qdrant Retrieve Tool`
+   - `Embeddings For Insert`
+   - `Embeddings For Retrieve`
+   - `Ollama Chat Model`
+   - `Send Telegram Reply`
+2. Для каждого включи `Retry on Fail` и выставь:
+   - `Max Tries = 5`
+   - `Wait Between Tries = 5000 ms`
+3. Убедись, что из среды `n8n` доступны:
+   - Telegram API (для `Telegram Trigger`)
+   - URL Ollama
+   - URL Qdrant
+4. Если снова падает на активации, временно отключи ветку `Telegram Trigger` и активируй ingest-ветку (`Webhook TG Inbox`) отдельно.
