Pantry move/expiry edit + smart shopping list with summary

- Move items between fridge↔freezer (freezer→fridge sets +7d or shelf life expiry, fridge→freezer clears expiry)
- Inline expiry date editor on fridge items (📅 button)
- Smart shopping list now shows recipe gaps (missing required slot ingredients)
- Summary card shows breakdown: X staple restocks, Y expiring, Z recipe gaps
