Bernhard Müller fb53b169a2 fix(community): migrate metering data timestamps from LocalDateTime to Instant to fix DST constraint violation ... Switch interval_start/interval_end from LocalDateTime to Instant across the entire metering data stack (entity, DTOs, parser, repository, services, controllers). This eliminates DST-related unique constraint violations that occurred when two different wall-clock times mapped to the same epoch millis during CET/CEST transitions. Key changes: - MeteringData entity: intervalStart/intervalEnd now Instant - XlsxMeteringDataParser: produces Instant via JVM timezone conversion - MeteringDataRepository: all queries use Instant parameters - MeteringDataService: simplified deduplicate() (Instant has no DST ambiguity) - Added hibernate.jdbc.time_zone=UTC and test profile for in-memory H2 - Added MeteringDataUploadIntegrationTest with real H2 database - Added DST-specific parser and service tests - All 216 tests passing		2026-07-24 13:23:35 +02:00
