feat: allow --list to accept item IDs for filtering

- Local and client/server modes now support ID-based filtering
- keep -l 1 2 3 lists specific items by ID
- keep -l --ids-only 1 2 3 outputs just those IDs
- Server API adds optional 'ids' query parameter to GET /api/item/
- KeepClient.list_items gains ids parameter
