feat: Paginierung für alle GET-List-Endpoints (#61)

Einheitliches Paginierungs-Pattern mit page, size und Multi-Field sort
für alle 14 List-Endpoints. Response-Format ändert sich von [...] zu
{ content: [...], page: { number, size, totalElements, totalPages } }.

Backend:
- Shared Kernel: Page<T>, PageRequest, SortField, SortDirection
- PaginationHelper (SQL ORDER BY mit Whitelist), PageResponse DTO
- Paginated Methoden in allen 14 Domain-Repos + JDBC-Implementierungen
- Safety-Limit (500) für findAllBelowMinimumLevel/ExpiryRelevantBatches
- Alle List-Use-Cases akzeptieren PageRequest, liefern Page<T>
- Alle Controller mit page/size/sort Query-Params + PageResponse

Frontend:
- PagedResponse<T> Type auf nested page-Format aktualisiert
- Alle 14 API-Client-Resourcen liefern PagedResponse mit PaginationParams
- Alle Hooks mit Pagination-State (currentPage, totalPages, pageSize)
- Alle List-Screens mit Seiten-Navigation (Pfeiltasten) und Footer

Loadtest:
- Podman-Support im justfile (DOCKER_HOST auto-detect)
- Verschärfte Performance-Schwellwerte basierend auf Ist-Werten
