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.
