Subject: [PATCH] fix: show response time in chart for upside down mode

When upside down mode is enabled, successful checks are marked as DOWN
but the response time chart was only showing ping for UP status.

This fix checks if the monitor has upside down mode enabled and shows
ping for both UP and DOWN status in that case, while maintaining the
original behavior for normal monitors.

Fixes #6038
