As discussed with @luizarakaki, rather than modify the legacy `SchedulePicker` to work with this use case, I made a new version of it - a `Schedule` component - that uses Mantine and a better (though imperfect) approach to localization. For now, the dropdowns are not vertically aligned in this Schedule picker - something I can try to remedy later if that is important.

Tests for the Schedule component will be added in a follow-up PR.
