Subject: [PATCH] test: cover UserPasswordSection and
 CorrespondenzFilterControls

UserPasswordSection: input rendering, type=password attribute,
required-prop propagation in both directions.

CorrespondenzFilterControls: dual date label rendering, both DateInput
ids, value hydration from fromDate/toDate, change-event smoke check.

Refs #496.
