Fix chat to use exact same API logic as voice agent
Changes: - Use anandk credentials (same as julia-agent) - Add normalizeQuestion() function to transform questions into format WellNuo API understands - "how is my dad" → "how is dad doing" - Remove user's SecureStore credentials - Use cached token with auto-refresh on 401 This makes text chat return real Ferdinand sensor data just like voice calls do. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
