fix(ci): replace fake action SHA pins with version-faithful real SHAs

These pins were partial-prefix-corruption fakes — fabricated SHAs that
share a prefix with a real version's SHA but have fabricated suffixes,
slipping past visual review. Verified fake via `gh api commits/<sha> ->
422`.

The fix preserves the version the author originally intended (read from
the `# vX.Y.Z` comment alongside each pin), rather than blindly bumping
to latest. This is important for actions where check-name reporting can
differ between major versions (e.g. CodeQL) — keeping the same major
preserves any branch-protection contexts that reference check names.
