Add container grammar with get-all and targeting support

- Update _find_container to use targeting module (prefix + ordinal)
- Update cmd_put to use find_in_inventory directly
- Add 'get all from <container>' support with portable item filtering
- Add comprehensive tests for all container grammar features
