The Diagnostics page now tells you the truth about your error screen..

The error-screen row used to answer "is Tracy installed?" — so a site running xWhoops was told "Not installed" while Whoops was holding the handlers. It now reads what XOOPS 2.7.3 publishes: who owns the screen, where that ownership came from, and whether anything needs looking at. Two modules fighting over it, or one claiming it and quietly failing, is now visible instead of silent.

Also fixes a false "handler drift" warning that appeared on every healthy install, and a toolbar toggle that could erase your recorded error-screen owner.

Requirements: XOOPS 2.7.0+ and PHP 8.2+. First beta; feedback welcome.
