Sync base-images v0.5.76, Go 1.25.10, lib-helm 1.71.11

[duckhawk]

Description

Automated tooling sync for snapshot-controller (scheduled sync_storage_modules_tooling.py).

• BASE_IMAGES_VERSION: v0.5.74 → v0.5.76 in .github/workflows/*.yml.
• Go: go directive already 1.25.10 in scanned api/, images/ and hooks/ modules.
• lib-helm: replace chart bundle with deckhouse_lib_helm-1.71.11.tgz (previous: 1.71.9).

Why do we need it, and what problem does it solve?

Keeps the module aligned with the latest deckhouse/base-images release and deckhouse/lib-helm
so CI and image builds use current base image digests, Go toolchain version, and Helm library charts.

What is the expected result?

• Pipelines resolve BASE_IMAGES_VERSION to the new (or current) tag and download matching base_images.yml.
• Go code under api/, images/ and hooks/ declares the same Go version as the default builder/golang-bookworm image.
• charts/ contains the current deckhouse_lib_helm-*.tgz when an update was required.

Checklist

• The code is covered by unit tests.
• e2e tests passed.
• Documentation updated according to the changes.
• Changes were tested in the Kubernetes cluster manually.
