feat(catalog): add qdrant 1.18.2 chart

- Pull upstream qdrant-helm chart v1.18.2 (appVersion v1.18.2)
- Add PaaSup custom overrides: custom-values.yaml, dip-values.yaml
  (ingress.ingressClassName=apisix), dip resource/volume quotas
- No breaking changes to existing overrides vs 1.12.4; helm lint passes,
  image renders as docker.io/qdrant/qdrant:v1.18.2
