Fix: AudioPlayback no longer requires network when clips exist

Resolves #229

Problem:
AudioPlayback test was forcing network connections even when audio
files were already present locally, causing tests to fail in offline
environments.

Solution:
- Add --enable-network-download flag (opt-in, default: disabled)
- Add audio_check_clips_available() to check files before network ops
- Implement smart network gating: only connect if files missing AND flag enabled
- Auto-enable network download when WiFi credentials provided via CLI
