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).
