BlackMark 6840d9df88 Audio overrides: lossless UTF-8 name round-trip (no high-bit collision) ...

The per-game override store keyed and persisted image names through narrow(), which
masked each character with & 0x7F, and widen() used the full byte -- not a true
inverse. So a non-ASCII exe name was corrupted on reload, and two names differing
only in their high bits collapsed onto the same key (e.g. U+00E9 'é' masked to
'i', so "café.exe" collided with "cafi.exe").

Use real WideCharToMultiByte/MultiByteToWideChar(CP_UTF8) so the round-trip is
lossless for any Unicode name. ASCII names are byte-identical under UTF-8, so
existing override files stay compatible.

audio_overrides_test gains a high-bit-collision case (café vs cafi, built from a
code point to keep the source ASCII) plus a non-ASCII persist/reload check -- both
of which the old 7-bit mask failed.
