fix(security): resolve Scorecard vulnerability and token-permission alerts

- Bump explorer's brace-expansion (minimatch dep) 5.0.8 -> 5.0.9 and
  nanoid (postcss dep) 3.3.16 -> 3.3.18, fixing GHSA-rgw5-rvv9-x895 and
  GHSA-2v37-7h3g-55p8 (both DoS via unbounded input, both within the
  existing caret ranges declared by their parents).
- Move codeql.yml and defender-for-devops.yml's security-events: write
  (and codeql.yml's actions: read) from workflow-level down to their
  single job, matching Scorecard's Token-Permissions ideal of a
  read-only top-level default with sensitive scopes granted only where
  used.
