Fix wxNotebook background colour in dark mode

After the changes of f8363719d4 (Preserve wxNotebook custom colours upon

Log Message:
-----------
Treat truncated reads as errors in wxDataInputStream

Reading from a truncated stream returned values built from partially
or completely uninitialised buffers, e.g. ReadString() decoded the
unread tail of its temporary buffer and the fixed size readers returned
whatever happened to be on the stack. Check that all the requested bytes
were actually read and, if not, mark the input stream as being in error
and return an empty/zero value instead of silently wrong data.

Closes #26600.

Log Message:
-----------
Map wxDF_TEXT to text in UTF-8 encoding in wxOSX

Don't use legacy encoding for it, this was unexpected and resulted in
e.g. wxClipboard::IsSupported(wxDF_TEXT) returning false when there was
text on the clipboard and IsSupported(wxDF_UNICODETEXT) returned true.

On current systems text and Unicode text are the same thing, so make
behaviour of wxDF_TEXT consistent with wxDF_UNICODETEXT.

See #26552.

Closes #26565.
