fix(preview): add missing font MIME types to web server

- Added MIME type mappings for .otf, .woff, and .woff2 font formats
- Fixed missing break statement after .wav case (was falling through to .mp4)
- Fonts now load correctly in editor preview without 404 errors
- Resolves OTS parsing error messages in console

The web server was already serving project directory files correctly,
but browsers were rejecting font files due to missing/incorrect MIME types.
