Non-standard WAV audio tracks

• CUE/WAVE tracks that are not 44.1 kHz stereo 16-bit PCM now convert. Both encoders reject other WAVE formats: chdman reports an unsupported sample rate and the built-in CHDSharp encoder says Unsupported samplerate - only 44100 is supported. The app now detects such tracks before encoding and writes a 44.1 kHz stereo 16-bit PCM copy in a private work directory. This covers 22.05 kHz, mono, 8/24-bit and float rips, including Sega CD sets and other non-CD-standard sources. Windows uses NAudio; Linux/macOS use ffmpeg from PATH.
• Only the affected track is reworked. The cue rework fast path stages the work directory on the cue's volume and references the disc image in place, so a multi-hundred-MB image is not copied just to normalize one audio track. When a same-volume directory is unavailable or the names require the full copy path, the full work directory normalizes the track there. The user's original files are never modified.
• A failed normalization is treated as user data. A corrupt or unsupported WAVE track is logged with the decoder's reason and no longer creates a bug report.

Code quality

• Remaining CodeQL code-scanning alerts resolved; code scanning reports zero open alerts.
• Meziantou.Analyzer updated to 3.0.322.

Verification

• Test suite: 1,299 tests pass (1,270 unit + 29 integration-tagged).
• JetBrains InspectCode: zero warnings and zero errors.
