ci: bump standards reusable-workflow SHA pins to current main (fc7abf5)

Resolves stale-pin contribution to CI reds. Target SHA picks up:
  - fc7abf5 scorecard.yml workflow-level permissions fix
  - 7814dc6 governance Java-shim exemption
  - 55da6b3 scripts/spdx-inject-copyright.sh
  - d7c3b8f canonical wrapper SHA pin sweep

No SPDX/licence content changes; pin-only mechanical bump.
