feat(logging): add LOG_ADMIN_HIDE setting and update logging functionality

Introduce a new configuration option `LOG_ADMIN_HIDE` to control the visibility of admin-generated events in the logs. Update the logging retrieval functions to respect this setting, ensuring that admin actions can be hidden from the "All message logs" UI and CSV exports. Additionally, enhance the README with detailed logging configuration options for better clarity.
