The Debug system plugin's setting Logging tab / Logging fieldset / "Log Entries" (PLG_DEBUG_FIELD_LOGS_LABEL, param logs) has a different default value of 1/true/ON in the settings, but false/0/OFF in the code.

Result is that as long as the DEBUG plugin settings have not been saved, the logs/deprecation tab of the debug bad are not displayed.

XML file default setting: https://github.com/joomla/joomla-cms/blob/4.0-dev/plugins/system/debug/debug.xml#L227
PHP file default setting: https://github.com/joomla/joomla-cms/blob/4.0-dev/plugins/system/debug/debug.php#L179

Steps to reproduce the issue

• Fresh Joomla install
• Turn debugging and logging on in global configuration
• Open the debug bar by clicking the joomla logo at top bottom

Expected result

See "Log", "Deprecated" and "Deprecation notices" tabs on the right of "J! Info Request Session Profile Queries" tabs.

Actual result

Seeing only "J! Info Request Session Profile Queries" tabs.

Then when just saving the Joomla plugin Debug settings WITHOUT changing them, those See "Log", "Deprecated" and "Deprecation notices" tabs suddenly display on the right of "J! Info Request Session Profile Queries" as expected.

System information (as much as possible)

Vanilla Joomla 4.0.2, on any platform.
