Development: Adopt openapi-generator-angular22 1.0.0 (incl. generator PR #5)

Switch the OpenAPI client generator from de.tum.cit.aet:openapi-generator-angular21:1.1.0
to openapi-generator-angular22:1.0.0 (renamed for the Angular 22 line; incorporates the
generator's PR #5 improvements) and regenerate the committed Angular client.

Generator changes surfaced in the regenerated client + the required Artemis adaptations:
- Model files now live in `openapi/model/` (singular, honoring modelPackage) instead of the
  previous `openapi/models/`. Codemod: rewrite `app/openapi/models/` -> `app/openapi/model/`
  across 53 app/spec files.
- File-download endpoints now return `Observable<HttpResponse<Blob>>` (was `Observable<Blob>`);
  unwrap `response.body` in the tutorial-groups CSV export consumer + its spec.
- Enums additionally emit a runtime `const` object alongside the existing string-literal union
  type (backward compatible), and array query params serialize as repeated params (Spring
  accepts both).

Verified locally: production build 0 errors; full Vitest suite 15,869/15,869 pass.

Note: openapi-generator-angular22:1.0.0 is not yet on Maven Central (only publishToMavenLocal);
CI never runs openApiGenerate (committed client), so this does not affect CI. Publishing to
Maven Central (needs Sonatype creds) is a follow-up for team-wide regeneration.
