refactor: OffsetDateTime-Migration, atomare Batch-Sequenznummern und Quantity.reconstitute-Overload

Browse source 
- LocalDateTime → OffsetDateTime (UTC) in allen Domain-Klassen, JPA Entities, DTOs und Tests
- Liquibase-Migration 017: TIMESTAMP → TIMESTAMP WITH TIME ZONE für bestehende Spalten
- Custom DateTimeProvider für Spring Data @CreatedDate-Kompatibilität mit OffsetDateTime
- Neue Sequenztabelle (016) mit JPA Entity + PESSIMISTIC_WRITE Lock statt COUNT-basierter
  Batch-Nummernvergabe (Race Condition Fix)
- Quantity.reconstitute(amount, uom) 2-Parameter-Overload für bessere Lesbarkeit
