phpdebugbar upgrade

[brianteeman]

The version of phpdebugbar that we use is v2.2.6 released Dec 26, 2025
The current version of phpdebugbar is v3.8.1 released October 25, 2026

One of the main differences is that it uses vanilla es6 javascript instead of jquery

It would be good to upgrade our version so that at least we dont need to use jquery but there are 300+ commits since the version we use was released
