coreutils sort:Align sort debug key annotations with GNU coreutils

Summary:

Add comprehensive fixture files for sort --debug key annotation output, including locale-specific expectations. Refactor tests to share a helper and split locale-aware coverage, matching GNU sort’s behavior. Ensure “no match for key” annotations render identically to the reference shell script.
