fix(runtime): bump ingress-nginx for mgmt Kubernetes 1.35

[plural-copilot]

Summary

• bump the bootstrap runtime chart ingress-nginx dependency from chart 4.14.1 to 4.15.0 for both public and private ingress releases
• refresh the vendored runtime chart dependency tarball and Chart.lock
• bump the runtime chart version from 0.1.36 to 0.1.37 so consumers can pick up the remediation

Why

Mgmt runtime currently sources ingress-nginx from the external bootstrap runtime chart. The pinned 4.14.1 release is the remaining Kubernetes 1.35 blocker. Upstream repository reality includes the preferred target ingress-nginx app 1.15.0 / chart 4.15.0, so this PR moves bootstrap directly to that compatible release.

Verification

• confirmed upstream ingress-nginx chart 4.15.0 exists and maps to app 1.15.0
• ran containerized helm dependency update/build for charts/runtime
• ran containerized helm lint charts/runtime

Consumer impact

Yes — a consuming version bump will be required in pluralsh/plrl-up-demos after this merges, because the bootstrap runtime chart version changes to 0.1.37 and that consumer must pick up the new chart version to receive ingress-nginx 4.15.0.
