User types in IDA 9.1 type editor

[shrddr]

In IDA 9.1, user types are highlighted with "IDA Colors > Syntax > User 1", which is not being set by the theme and is too dark by default

I suggest changing it to maybe R 86 G 156 B 214 (default color in Visual Studio for "C/C++ User Keywords")

Looking how it's being set by builtin dark theme I guess this should work

text_area_t
{
    qproperty-user1-fg: #569cd6;
}
