fix: Resolve npm audit vulnerabilities, ESLint errors, and PHP quality issues

Add npm overrides for critical/high transitive dependency vulnerabilities
(babel-traverse, fast-xml-parser, immutable, json5, minimatch,
serialize-javascript). Fix ESLint import/no-unresolved by adding
@conduction/nextcloud-vue alias to resolver config. Remove unused Delete
import in OrganisatieIndex.vue. Include prior PHP service fixes for
AangebodenGebruikService, ArchiMateExportService, and
ArchiMateImportService.
