Fix production-sync-testing.md guide and sanitize-logs.sh script

- Fix shebang in sanitize-logs.sh from #!/bin/bash to #!/usr/bin/env bash for NixOS compatibility
- Update sanitizer defaults from 100/20 to 200/100 chars for better log readability
- Fix CLI argument names in guide: --sync-bootstrap-relay -> --sync-bootstrap-relay-url
- Fix CLI argument names in guide: --git-path -> --git-data-path

These issues were discovered during first-time testing of the production sync testing guide.
