fix: improve Windows menuconfig style compatibility

[eastWillow]

This patch fixes the menuconfig style issue on Windows:

1. "back" is not a valid color name in _NAMED_COLORS.
2. The Windows Python environment does not support -1 as a color value.

To improve cross-platform compatibility, the background color has been explicitly set to black.

Summary by cubic

Fix Windows menuconfig styling by replacing the invalid background color “back” with “black” in the path style. This avoids Windows terminal color errors (-1 not supported) and ensures consistent, readable colors.

Please focus on improving sysprog21/Kconfiglib, as the Mado project is about to migrate from its old copy of Kconfiglib to the refined version.

1. Make config target use refined Kconfiglib if available
2. Maintains fallback to local tools for environments without Kconfiglib.

Don't do that. The directory tools/kconfig will be completely replaced with sysprog21/Kconfiglib. You should validate the Windows compatibility for that.

I’ve validated that sysprog21/Kconfiglib works correctly on Windows.
It runs fine in my environment.

python3.13 -m menuconfig configs/Kconfig

Is there anything I can do to help prevent issues for other Windows users like me?
Or should I just close this pull request?
