Fix "selected user is invalid" when granting bundle to user with null name

Filament's Select uses getOptionLabelUsing to validate the chosen value;
returning a blank label causes the "in" rule to reject it. The bundle
grant action returned `User->name`, which is null for some users.

Use `getFilamentName()` so the label falls back through display_name,
name, then email, ensuring a non-blank result for any existing user.
