M7: release polish — export/import, docs, easy docker push
- Easy docker push (MQTTower ergonomics + the image push it lacks): VERSION file →
version-tag.yml (semver-guard auto-tag) → docker-publish.yml (buildx multi-arch → GHCR,
registry centralized for one-line retarget to git.finalfactory.de) + ci.yml + build-and-push.ps1.
- Verified end to end: deploy/Dockerfile builds; docker compose stack (app + timescaledb) comes
up healthy; /healthz and the dashboard respond in-container.
- JSON config export/import (ExportService) with id remapping on restore + GET /export, POST
/import endpoints; round-trip test preserves meter→type, meter-scoped tariff, category links.
- README, HA/Tasmota/MQTT wiring guide (docs/wiring.md), Unraid template.
- CLAUDE.md updated to reflect the built codebase.
- i18n: locale-aware number/currency formatting (de-DE); full de UI string localization deferred.
95 tests green (56 Core + 39 integration).
