fix: assertNotified() and assertNotNotified() without args now assert (#19500)

* fix: make assertNotified() and assertNotNotified() without args assert

When called without arguments, both methods previously hit a `blank()`
check and returned early — making no assertion at all. They always
passed, even when the assertion should have failed.

Now assertNotified() without args asserts that at least one notification
was sent, and assertNotNotified() without args asserts that no
notifications were sent.

Fixes filamentphp/filament#19499
