VisualEars FA32M FastConformer Persian ASR WebGPU Demo

Browser WebGPU demo for `Reza2kn/visualears-fastconformer-fa32m-streaming-bpe1024-onnx-fp16`.

This revision uses the corrected FA32M contract: NeMo-compatible fbank features (normalize=NA, preemphasis, centered STFT, Slaney mel filters) plus the processed_signal_length ONNX input. That fixes the prior symptom where the app detected speech/finished utterances but decoded mostly empty transcripts.

Parity gate before switch: 267/269 exact transcript matches (99.26%) vs the source PyTorch NeMo preprocessor + encoder + auxiliary CTC path; ONNX non-empty transcript rate 266/269 (98.88%) on the short/noisy VisualEars269 set.
