Subject: [PATCH] fix: black BackInfo bg + wrong taskbar accent color

BackInfo.ini:
- AutoBackground=0: don't read live desktop color during deployment;
  Windows hasn't propagated the registry background color to the
  live session yet, so AutoBackground reads black
- BackgroundColor=4668194: explicit COLORREF for #223B47
  (was 2097152 = 0x200000 = RGB(0,0,32), near-black)

05-personalization.ps1:
- Add Explorer\Accent\AccentColorMenu = 0xFF473B22
- Add Explorer\Accent\StartColorMenu = 0xFF473B22
  Windows taskbar reads AccentColorMenu for its color when
  ColorPrevalence=1; DWM\AccentColor only controls title bars.
  Without these keys the taskbar shows Windows default blue
  (RGB 130, 232, 253 = Windows 11 "Steel" default accent).
