fix(compose): use external postgres volume + city-service ENV

- docker-compose.yml: postgres uses microdao-daarion_postgres_data (external)
- docker-compose.yml: city-service connects to dagi-postgres:5432/daarion + NATS_URL
- docker-compose.city-space.yml: added dagi-postgres, dagi-nats as services
- docs/DEPLOY_ON_SERVER.md: added restart instructions without data loss

Closes TASK_PHASE_DOCKER_COMPOSE_CITY_SERVICE_POSTGRES

 ## 🔄 Updates & Maintenance
 
+### Docker Compose для Postgres та City-Service (NODE1)
+
+**⚠️ ВАЖЛИВО:** На production (NODE1) використовується external том `microdao-daarion_postgres_data`.  
+Не запускайте `docker compose up` без списку сервісів — це може створити нові порожні контейнери!
+
+**Правильний запуск Postgres і City-Service:**
+
+```bash
+# 1. Спочатку перевірте, що external том існує
+docker volume ls | grep postgres_data
+
+# 2. Якщо тому немає — створіть його (тільки на свіжому сервері)
+docker volume create microdao-daarion_postgres_data
+
+# 3. Запуск Postgres (використовує existing volume)
+docker compose up -d postgres
+
+# 4. Запуск City-Service (без перезапуску залежностей)
+docker compose up -d city-service --no-deps
+
+# 5. Перевірка
+docker ps | grep -E "(postgres|city-service)"
+curl https://daarion.space/api/nodes/list
+```
+
+**Альтернативний файл (city-space):**
+
+```bash
+# Якщо використовуєте docker-compose.city-space.yml
+docker compose -f docker-compose.city-space.yml up -d dagi-postgres
+docker compose -f docker-compose.city-space.yml up -d city-service --no-deps
+```
+
+**Перевірка після запуску:**
+
+```bash
+# API ноди
+curl -s https://daarion.space/api/nodes/list | jq .
+
+# API агентів
+curl -s https://daarion.space/api/agents/ag_daarwizz | jq .
+
+# MicroDAO
+curl -s https://daarion.space/api/microdao/daarion | jq .
+```
