Fix the verify email user action

[soymgomez]

Summary

• fix the Verify email action on the users table, which threw a LogicException instead of sending the verification email:

  The action [verify-email] is attempting to access the selected records query from the table, but it is not using [accessSelectedRecords()], so they are not available.

• the action closure type-hinted an unused Builder $query parameter. Filament resolves a Builder parameter as the selected records query, which a record action does not provide, so evaluating the closure failed before the notification was sent
• drop the unused parameter (and the now unused Builder import) and give the closure an explicit void return type, matching the neighbouring reset-two-factor action
• add a regression test that calls the action on an unverified user and asserts the VerifyEmail notification is sent

Validation

• the new test fails on main with the LogicException above and passes with the fix
• vendor/bin/pest: 1135 passed (4162 assertions), after composer build
• vendor/bin/pint --test: passed
• vendor/bin/phpstan analyse src/Filament/Resources/Users/UserResource.php: no errors
