Profile avatar cloud upload + test bundle ID

- Profile avatar now uploads to MinIO cloud storage via /auth/avatar endpoint
- Added loading indicator (ActivityIndicator) during avatar upload
- Avatar loads from cloud URL (user.avatarUrl) first, with SecureStore fallback
- Changed iOS bundleIdentifier to com.serter2069.wellnuo.test (test account)
