Fix grant-to-user Select validation by adding getOptionLabelUsing (#394)

The searchable user_id selects on the plugin/product "Grant to User"
actions defined getSearchResultsUsing() but not getOptionLabelUsing(),
so Filament could not build the `in` validation rule and threw a
LogicException on submit. Adds getOptionLabelUsing() to all three
actions and covers the action submission path with tests.
