feat: auto-generate ibsystem dashboard from project documentation ...

- sync_names.py now also generates ibsystem_dashboard.yaml:
  - Device cards titled '{location} (ID{n})' from project YAML
  - Entity names from io.description instead of hardcoded 'DO.0/1/2/3'
  - WSZYSTKIE ON/OFF buttons updated with current device list
  - Copies dashboard to HA via SSH (key auth .244→.151)
- Trigger: any change to proj-ib-lighting-rs485-zarki.yaml

feat: auto-sync entity names from project documentation ...

- Add sync_names.py: parses proj-ib-lighting-rs485-zarki.yaml,
  updates friendly_names in ibsystem2mqtt.yaml, restarts service
- Add ibsystem-sync-names.path: systemd path watcher on project YAML
- Add ibsystem-sync-names.service: oneshot service running sync_names.py
- Update config.yaml: 85 friendly_names from all devices (ID2-ID41)

Usage: edit /smart-home/proj-ib-lighting-rs485-zarki.yaml → HA updates automatically
Manual: python3 /ibsystem/sync_names.py [--dry-run]
