feat(transcription): add Xiaomi MiMo ASR provider (mimo-v2.5-asr)

Browse Source 
Add support for Xiaomi MiMo ASR as a third transcription backend alongside
Groq and OpenAI Whisper. Xiaomi ASR uses the /v1/chat/completions endpoint
with base64-encoded audio input, rather than the standard Whisper multipart
upload format.

## Providers
> [!TIP]
> - **Voice transcription**: Voice messages and WebUI/desktop microphone input use the shared top-level `transcription` settings. By default Groq Whisper is used; set `transcription.provider` to `"openai"` for OpenAI Whisper or `"openrouter"` for OpenRouter speech-to-text models. API keys still live in the matching `providers.<provider>` config.

> - **MiniMax (Mainland China)**: If your API key is from MiniMax's mainland China platform (minimaxi.com), set `"apiBase": "https://api.minimaxi.com/v1"` in your minimax provider config.
> - **MiniMax thinking mode**: Use `providers.minimaxAnthropic` when you want `reasoningEffort` / thinking mode. MiniMax exposes that capability through its Anthropic-compatible endpoint, so nanobot keeps it as a separate provider instead of guessing MiniMax-specific thinking parameters on the generic OpenAI-compatible `minimax` endpoint. It uses the same `MINIMAX_API_KEY`. Default Anthropic-compatible base URL: `https://api.minimax.io/anthropic`; for mainland China use `https://api.minimaxi.com/anthropic`.
