Fix Sherpa local ASR state sync

[weikeyi]

User description

摘要

• 在设置变更和 Windows 启动时，将持久化的 active ASR provider 同步到后端运行时的 credentials vault，避免前端偏好与实际听写 provider 状态不一致。
• 让 Sherpa ONNX catalog/download 状态与已解压的 release archive 资源保持一致，包括 Qwen3 tokenizer/ 目录校验和 downloadedBytes 统计。
• 更新前端 Sherpa ONNX 状态展示与删除可用性：Overview 会在 ASR/LLM provider 变化时刷新 credentials 状态，Sherpa 模型存在部分下载或已解压资源时允许删除。
• 已基于最新 beta 解决设置页重构冲突：旧 Settings.tsx 不再进入本 PR，新版 settings/ProvidersSection.tsx 中已包含 sherpa-onnx-local 的本地 provider 识别逻辑。

Here are some key observations to aid the review process:

⏱️ Estimated effort to review: 3 🔵🔵🔵⚪⚪

🧪 PR contains tests

🔒 No security concerns identified

⚡ Recommended focus areas for review Incomplete dir check The special case for qwen3-asr-0.6b-int8 only checks path.is_dir(), so any empty or partially extracted tokenizer/ directory is treated as valid. That can mark a broken install as cached and allow the UI/download logic to skip re-downloading even though the model is unusable. fn required_path_is_dir(alias: &str, required: &str) -> bool { matches!((alias, required), ("qwen3-asr-0.6b-int8", "tokenizer")) }
