Add $state errorMessage + role=alert banner to ChronikFuerDichBox. Both enhance callbacks
now inspect result.type and set the error message on 'failure' or 'error'; errorMessage
is cleared on each new submit attempt.
Upgrade both test files to the mockFormResult pattern (via vi.hoisted) so the result
callback is exercised. Add a failing-action test in each file that asserts role=alert
appears after a form submit with type='failure'.
Fix bare Function cast → explicit typed cast to satisfy @typescript-eslint/no-unsafe-function-type.

Dismiss (X) button and mark-all-read button now submit forms to
/aktivitaeten?/dismiss-notification and /aktivitaeten?/mark-all-read respectively.
Props renamed onMarkRead/onMarkAllRead → optimisticMarkRead/optimisticMarkAllRead.
aktivitaeten/+page.svelte drops the now-deleted onMarkRead/onMarkAllRead wrapper functions
and passes notificationStore.optimisticMarkRead/optimisticMarkAllRead directly to the box.
Tests: $app/forms enhance mock added to both spec files so dismiss and mark-all assertions
work synchronously against form-submit events.
