fix(Reminders): migrate to @nextcloud/vue v9 API

Use the individual component import path for NcDateTimePickerNative
instead of the removed barrel export from '@nextcloud/vue'.

Replace 'v-model:value' with 'v-model' for NcTextField, since the 'value'
prop was renamed to 'modelValue' in @nextcloud/vue v9.0.0.
