feat: add MQTT subscriber for ESP32 camera status ingestion

generated from CubeCraft-Creations/Tracehound

Implements MQTT subscriber (internal/mqtt/subscriber.go) that:
- Connects to Mosquitto broker with auto-reconnect
- Subscribes to remoterig/cameras/+/status, +/heartbeat, +/announce
- Parses and validates incoming messages per MQTT contract
- Inserts status_logs with duplicate prevention
- Auto-detects recording state changes and manages recording_events
- Broadcasts camera status changes via SSE hub
- Camera auto-registration via announce (MAC-based, sequential cam-NNN)
- Heartbeat watchdog marks cameras offline after 120s silence
- Wired into main.go with graceful degradation (warns if broker unreachable)

Dependency: github.com/eclipse/paho.mqtt.golang v1.5.0

Closes CUB-232.
