- Add missing User type fields (first_name, last_name, email, avatar_url,
city, address) used in profile.tsx
- Fix expo-constants import to use namespace import (consistent with
rest of codebase)
- Replace placeholder production API URL with configurable value
- Fix avatar preset/color selection passing require() IDs to Image uri
by tracking local source separately
- Replace all relative fetch() calls with configured axios instance
(relative URLs don't resolve in React Native)
