fix: resolve golangci-lint failures in jfrog storage implementation

- Remove unused pathCache field from PublishedStorage struct
- Remove unused md5s accumulation in Filelist()
- Fix unchecked error return on expectedOut.Write in config_test.go
- Suppress unused linter on configFileYAML/configFileYAMLError constants
  (retained to avoid merge conflicts with feat/pls/gcs-support)
- Add --timeout=10m to golangci-lint workflow
- add back removed tests
