Azure was the only provider for the xiaochen voice. All TTS now routes through Minimax, so the provider factory, enum, and SDK dependency are no longer needed.

Pull request overview
This PR removes the Azure TTS implementation (previously only used for the xiaochen voice) and simplifies the TTS flow so all server-side synthesis uses the Minimax provider, along with associated dependency/env/docs cleanup.
Changes:
- Deleted the Azure TTS provider implementation and removed the
microsoft-cognitiveservices-speech-sdkdependency. - Simplified the TTS provider selection logic in
/server/api/reader/tts.get.tsto always use Minimax (and removed thexiaochenvoice option). - Removed Azure-related runtime config and deployment environment variables; updated docs/examples accordingly.
