Subject: [PATCH] feat: upgrade FunASR + add Fun-ASR-Nano & SenseVoice ASR
 backends
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Upgrade funasr from ==1.0.27 to >=1.3.7
- Add Fun-ASR-Nano (31 languages, Chinese dialects, recommended default)
- Add SenseVoice (ultra-fast 170x realtime, 5 languages)
- Keep original Paraformer as '达摩 ASR (中文经典)' for backward compat
- WebUI shows 3 FunASR options + Faster Whisper

Tested: routing logic verified for all backends (zh/en/ja/ko).
Resolves #2777
