Bump version to 1.17.0

- Neue Tabelle wp_kgvvm_parcel_cost_assignments für 1:N Zuordnungen
- CostRepository erweitert: get_assigned_entry_ids(), get_entry_ids_with_assignments(), assign_to_parcel(), unassign_from_parcel(), delete_assignments_for_entry()
- Admin: Neue POST-Action toggle_parcel_cost_assignment() mit Nonce-Sicherung
- Jahresabrechnung Parzelle: Rechte Seitenleiste zeigt alle Kostenpositions mit Zuordnungsstatus (✓ zugeordnet, ✗ nicht zugeordnet, – alle Parzellen)
- Berechnung: Kostenposten mit Beschränkung werden nur berechnet wenn Parzelle zugeordnet ist
- DataTransfer.php: parcel_cost_assignments in table_keys integriert für Export/Import
- DELETE-Handler bereinigt Zuordnungen beim Löschen einer Kostenposition
