Pull Request Overview

This PR updates documentation for Moodle's message API to reflect changes made in version 4.4+, where deprecated constants MESSAGE_DEFAULT_LOGGEDIN and MESSAGE_DEFAULT_LOGGEDOFF were replaced with MESSAGE_DEFAULT_ENABLED.

• Updates code examples to use the new MESSAGE_DEFAULT_ENABLED constant instead of the deprecated ones
• Updates documentation comments to reflect the simplified bit usage pattern
• Applies these changes consistently across multiple documentation versions (4.4, 4.5, 5.0, and current docs)
