The keystore atomic write used path.with_extension("tmp") producing
auth_tokens.tmp, while cleanup_orphaned_tmp_files only matched *.json.tmp.
A crash after the write but before the rename left an orphaned file
invisible to cleanup.
Fix: use path.with_extension("bin.tmp") to produce auth_tokens.bin.tmp,
and broaden the cleanup glob from ends_with(".json.tmp") to
ends_with(".tmp") so both JSON and binary temp files are caught.
