chore(ci): update GitHub Actions to latest versions

Update GitHub Actions dependencies across all workflows to their latest
stable versions to ensure compatibility, security patches, and latest
features. This includes checkout@v5, cache@v4, setup-node@v6, and
upload-artifact@v5. Also updates Swagger UI from v5.17.14 to v5.30.2
for improved API documentation rendering.

These updates address deprecation warnings and ensure continued
compatibility with GitHub Actions infrastructure.
