fix(sherpa-onnx.rn): add missing dpdfnet field to OfflineSpeechDenoiserModelConfig (Android SIGABRT)

[brainlybai]

Summary

Fixes #411. On Android, OfflineSpeechDenoiser.newFromFile aborts the process with SIGABRT under CheckJNI because the native JNI calls GetFieldID("dpdfnet", "Lcom/k2fsa/sherpa/onnx/OfflineSpeechDenoiserDpdfNetModelConfig;") on OfflineSpeechDenoiserModelConfig, but the Kotlin data class doesn't declare that field.

This PR adds the missing OfflineSpeechDenoiserDpdfNetModelConfig data class and the dpdfnet field on OfflineSpeechDenoiserModelConfig, matching upstream sherpa-onnx Java bindings.

Crash (before)

F DEBUG: #08 CheckJNI::GetField
F DEBUG: #11 libsherpa-onnx-jni.so Java_..._OfflineSpeechDenoiser_newFromFile+56
F DEBUG: #17 com.k2fsa.sherpa.onnx.OfflineSpeechDenoiser.<init>

Test plan

• Verified upstream sherpa-onnx/jni/speech-denoiser.cc queries the dpdfnet field unconditionally
• Verified the prebuilt libsherpa-onnx-jni.so shipped in 1.3.1-beta.1 references dpdfnet (binary grep)
• Applied the equivalent patch locally via pnpm patch — denoiser init no longer aborts
• Maintainer to verify on iOS (Swift handlers should be unaffected)

Notes

• Only Android is affected; iOS uses Swift handlers under ios/handlers/ and doesn't reflect on Kotlin classes.
• Default value of the new field is an empty OfflineSpeechDenoiserDpdfNetModelConfig(), so existing GTCRN-only callers are not affected at runtime.
