chore: CI cleanup — fix CodeQL build-mode, attestation perms, drop OWASP depcheck

- Set CodeQL build-mode to manual/none per language to suppress overlay-base warning
- Add artifact-metadata:write permission to docker build job for attestation storage
- Remove OWASP Dependency Check plugin and job (redundant with grype-gradle SBOM scan)
