Goals can now choose between milestone-based progress (existing) and
cumulative checkin-based progress (new). Cumulative mode supports
cross-unit conversion (e.g. kcal → g fat) via a configurable
conversion rate. New GoalCheckin model stores daily inputs; progress
auto-recalculates on every checkin C/U/D. Backup import/export covers
the new table. Frontend GoalDialog, GoalDetailPage and GoalPage cards
adapt to show cumulative progress or milestone progress based on
track_type.
