feat: remove Show All navigation card from entity grids

- Remove ShowAllCard component and all related functionality
- Remove showAllRoute, showAllQueryParams, and hideShowAll props
- Remove shouldShowAll computed property from EntityGrid
- Clean up ShowAll-related code from EntitySelectionStep and GiftedDialog
- Delete ShowAllCard.vue component file
- Update component documentation to reflect removal

This simplifies the entity selection interface by removing the navigation
card that allowed users to view all entities in a separate view.
