fix(backend): fix 2 CI test failures from media resolution changes

- test_multi_file_commit_error_path: provide execution_context kwarg
  now required by GithubMultiFileCommitBlock.run()
- test_non_media_string_field_still_reads_content: mock
  _infer_format_from_workspace to avoid event loop binding issue in CI
