fix: accept total_logs parameter in export_to_event function

Remove incorrect local calculation of total_logs from log_index and accept
it as a parameter instead. This fixes the bug where log_index=0 would
incorrectly be treated as a single-log scenario even in multi-log files.

The log suffix is now only appended when total_logs > 1, ensuring correct
naming for multi-log exports.

Updates all callers in examples and documentation to pass the correct
total_logs value from their context.
