fix(ci): clear OSSF Scorecard startup_failure

Fixes the OSSF Scorecard workflow, which failed at startup on every run.

**Cause:** reusable-workflow caller missing `security-events: write`+`id-token: write` (reusable perms are capped by the caller), and/or an illegal `timeout-minutes` key on a `uses:` job.

**Fix:** inject caller permissions and/or drop `timeout-minutes`. Pin preserved. Verified with actionlint. Part of an estate-wide Scorecard remediation.
