Fix OpenSSF Scorecard security issues in all workflow files

Updated all 13 GitHub Actions workflow files to address OpenSSF Scorecard
Token-Permissions and Pinned-Dependencies checks:

- Added SPDX-License-Identifier headers (AGPL-3.0-or-later)
- Added workflow-level `permissions: read-all` directive
- Added job-level permissions with minimal required scopes
- Pinned all GitHub Actions to SHA hashes with version comments:
  - actions/checkout@b4ffde6 # v4.1.1
  - github/codeql-action/*@662472033e021d55d94146f66f6058822b0b39fd # v3.28.1
  - ossf/scorecard-action@62b2cac # v2.4.0
  - trufflesecurity/trufflehog@8a8ef85 # v3.88.3
  - actions/setup-haskell@28c8ff1 # v1.1.5
  - actions/cache@6849a64 # v4.1.2

Files updated:
- codeql-analysis.yml
- codeql.yml
- comprehensive-quality.yml (11 jobs)
- generator-generic-ossf-slsa3-publish.yml
- guix-nix-policy.yml
- haskell.yml
- mirror.yml
- npm-bun-blocker.yml
- php-security.yml
- quality.yml
