1.0.6: Priority dishes, day rules, auto-assign CTA, tap-to-replace, export incomplete weeks, Sunday notification

- Dish.isPriority: mark dishes as priority; auto-assign gives them 2.5x weight
- Tag.dayRestriction: restrict tags to weekdays or weekend only
- Auto-assign CTA banner shown when there are empty slots (was hidden in context menu)
- Tap on filled slot opens picker to replace dish directly (no need to remove first)
- Export callout visible as soon as ≥1 slot is filled (not only when week is complete)
- WeekPlanShareView shows localized "TBD" / "Eating out" for empty/eating-out slots
- Second Sunday 17:00 push notification to plan next week
- DishDrawer sorts: priority first, then by historical usage, then alphabetically
- Search in SlotDishPickerSheet already shipped in 1.0.5 (verified ✓)
