[BUG] Ender3 V2 - Enhanced UI - Screen brightness stuck at half

[CRCinAU]

Did you test the latest bugfix-2.0.x code?

Yes, and the problem still exists.

Bug Description

It looks like the LCD Brightness option in the enhanced DWIN display doesn't seem to alter the LCD brightness.

On boot, the LCD seems to go to half brightness, but changing anything in the Advanced Settings does not get reflected in a brightness change of the LCD.

That was ok, maybe there was a problem with the last integration: #22778

As as temp fix I added to \Marlin\src\inc\Conditionals_post.h

#if EITHER(HAS_DWIN_E3V2, IS_DWIN_MARLINUI)
#define HAS_LCD_BRIGHTNESS 1
#define LCD_CONTRAST_MAX 255
#endif
