Fix flakey SchemaDialogView 'change text' JS test

Add a wait for the FormView autofocus timer (200ms) to complete before
typing, preventing a race condition where the autofocus moves focus away
from the target field on slow CI machines. This matches the pattern
already used by simulateValidData in the same test file.
