NOISSUE - Update protobuf generated files and improve algorithm handling in runner service (#612)

* Update protobuf generated files and improve algorithm handling in runner service

- Bump protoc version from v7.35.0 to v7.35.1 in generated protobuf files.
- Refactor RunRequest message in runner.proto to use string paths for algorithm and requirements instead of byte arrays.
- Update runner service to handle algorithm and requirements paths, removing the need for temporary file creation.
- Enhance error handling for missing algorithm paths in the runner service.
- Modify tests to align with the new RunRequest structure and ensure proper file handling.
