Henrik RydgårdandClaude Opus 5 e4613a3487 WaveFile: don't assert-crash when the wav file couldn't be opened
__StartLogAudio ignored WaveFileWriter::Start()'s return value and set m_logAudio
either way, so a wav file that couldn't be opened - read-only or full audio
directory, most likely - left every subsequent mixed block calling
AddStereoSamples on a closed file. That opens with _assert_msg_(file, ...).

Also other minor fixes.
