Add format_number function to checker.py for improved subscription ID formatting

This update introduces a new `format_number` function that formats subscription IDs into a more readable format (e.g., converting 1000 to '1k'). The `check_logs` function has been modified to utilize this new formatting for both head subscription ID and last subscription ID in the status messages, enhancing clarity in log analysis and improving the overall readability of subscription status reporting.
