NutriTrace

Added

• Scan Label. On the Add/Edit Food screen, take a photo of a nutrition label and the AI Assistant fills in the values. Requires AI Assistant to be configured.

Changed

• Custom nutriment order is reflected in the food and meal editors. Reordering nutrients in Settings now changes their display order everywhere.
• Vitamin D, Calcium, Iron, and Potassium are visible by default on new installs, matching the FDA’s mandatory Nutrition Facts label fields.

Fixed

• kcal/kJ inconsistencies when energy unit was set to kJ. Food editor, diary footer, meal totals, statistics charts, goals, weekly summary email, and push notifications all respect the chosen unit now. Internal storage stays kcal; only the display converts. (Issue #38)
• Single-user mode: only the first food item added each day was visible in the UI. A SQLite quirk meant NULL user_id rows never collided on upsert, so each save inserted a new row instead of updating. A one-time migration on first boot recovers items already in the database. (Issue #37)
• AI features failed on Android when configured via server env vars. Smart Log voice (Trace hold-to-record), Scan Label, the chat panel, and Goal Insights all routed through a code path that didn’t send the auth token Android needs, so calls returned 401 even though the env-lock was set correctly. The voice path also threw “AI provider not configured” before it ever reached the proxy. Both gaps are closed. (Issue #36 followup)
