feat(docker): IoT Bridge Phase 1.5 - Docker Container Build

- Multi-stage Dockerfile für minimales Production Image (71MB)
  - Builder Stage: gcc + pip install mit --user
  - Runtime Stage: python:3.11-slim, non-root user (bridge:1000)
  - Fix: Python packages nach /usr/local/lib/python3.11/site-packages
- .dockerignore für optimierte Build-Context
- requirements.txt erweitert mit PyYAML>=6.0
- config.yaml.dev für lokale Development-Tests
  - Mosquitto container integration
  - Vorbereitet für docker-compose.dev.yaml

Container tested:
  - Erfolgreicher Build (Image: 8b690d20b5f7)
  - Runtime test mit produktivem MQTT Broker
  - Session Detection funktioniert
  - Event Queue verarbeitet Messages

Phase 1 (MQTT Bridge) ist damit vollständig containerisiert.

 ### 1.5 Docker Container Build
-- [ ] `Dockerfile` finalisieren (multi-stage, non-root user)
-- [ ] `docker build -t iot_mqtt_bridge_for_odoo .`
-- [ ] `docker run` mit Volume für config.yaml
-- [ ] Health-Check (HTTP endpoint optional)
+- [x] Multi-stage `Dockerfile` finalisiert
+  - Builder Stage: gcc + pip install dependencies
+  - Runtime Stage: minimal image, non-root user (bridge:1000)
+  - Python packages korrekt nach /usr/local/lib/python3.11/site-packages kopiert
+- [x] `.dockerignore` erstellt (venv/, tests/, __pycache__, logs/, data/)
+- [x] `requirements.txt` erweitert mit PyYAML>=6.0
+- [x] `docker build -t iot_mqtt_bridge:latest`
+  - 3 Build-Iterationen (Package-Path-Fix erforderlich)
+  - Finale Image: 8b690d20b5f7
+- [x] `docker run` erfolgreich getestet
+  - Volume mount: config.yaml (read-only)
+  - Network: host (für MQTT-Zugriff)
+  - Container verbindet sich mit mqtt.majufilo.eu:8883
+  - Sessions werden erkannt und Events verarbeitet
+- [x] Development Setup
+  - `config.yaml.dev` für lokale Tests (Mosquitto + Odoo)
+  - `docker-compose.dev.yaml` erweitert mit iot-bridge service
 
-**Test:** Container startet, subscribed MQTT, loggt Events
+**Test:** ✅ Container läuft produktiv, empfängt MQTT, erkennt Sessions
+**Docker:** ✅ Multi-stage build, 71MB final image, non-root user
