[Enhancement] generalize active menu highlight feature

[pxpm]

We have a little problem in our active menu highlight feature.

At the moment each theme implements their own active menu selector script, that leads to inconsistencies and bugs that happen in one theme, but work in other.

We still have a problem that menu-item and menu-item?active=1 don't work properly when used as menu urls, and to fix it, we need to push a fix to multiple places.

Ideally we would create a script that can be used by any theme, centralized in CRUD project.

Hmm...

• If it's an S, yes
• if it's an M, maybe
• if it can be 2x M, no

😀

I think some JS in our "UI" is inevitable, and could be useful to theme developers yes:

• js to make the menu items active or not; and maybe check which item is already active if any;
• js to turn dark mode on/off/system (if bootstrap doesn't already have one);

I'll think about this again when I finish the Bootstrap theme (1-2 weeks).
