fix(asr): validate MiMo credentials as ASR provider

[zouzhe1]

User description

摘要

修复小米 MiMo ASR 已选中后，快捷键启动听写仍误提示检查火山引擎 ASR 凭据的问题。

修复 / 新增 / 改进

• 修复 ensure_asr_credentials() 对 xiaomi-mimo-asr 的凭据分类。
• 将小米 MiMo ASR 归入 ASR API Key 类型校验，而不是默认落入火山引擎 App Key / Access Key 校验。
• 新增回归测试，确保 MiMo ASR 不会再被误分类为火山引擎凭据路径。

兼容

• 不包含：不修改 MiMo ASR 请求协议、不修改设置页字段、不修改火山 / Whisper / 百炼 / 本地 ASR 的运行协议。
• 对现有用户 / 本地环境 / 构建流程的影响：已选择小米 MiMo ASR 的用户会按 asr.api_key 校验启动听写，不再要求填写火山引擎凭据；其他 ASR provider 行为保持不变。

测试计划

• 命令：cargo test credential_gate_classifies_mimo_as_api_key_asr_provider --lib

• 结果：通过，1 passed; 0 failed

• 证据路径：openless-all/app/src-tauri/src/coordinator/tests.rs

• 命令：cargo test mimo --lib

• 结果：通过，7 passed; 0 failed

• 证据路径：openless-all/app/src-tauri/src/asr/mimo.rs
