test: Add Voice service tests (546 lines, 22 tests)
Created comprehensive test suite for voice/speech recognition service: - OpenAI Whisper transcription integration - Azure OpenAI configuration support - Audio transcription with language detection - Activity extraction from natural language (GPT-4o-mini) - Support for 6 activity types (feeding, sleep, diaper, medicine, activity, milestone) - Multi-language support (en, es, fr, pt, zh) - Process voice input (transcribe + extract) - Generate clarification questions for ambiguous input - Save user feedback on voice command accuracy - Error handling and fallbacks Tests cover: - Standard OpenAI and Azure OpenAI configurations - Transcription with language parameter - Activity extraction for all types (feeding, sleep, diaper, medicine) - Unknown activity detection - Child name inclusion in prompts - Clarification question generation - Feedback persistence - Error scenarios and service unavailability Total: 546 lines, 22 test cases Coverage: Whisper transcription, GPT extraction, feedback 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
