chore(ui): drop the now-unused native date-input primitives

Every callsite moved to DateField/DateTimeField, which honour the
user's date-format preference; the native DateInput/DateTimeInput
wrappers have no remaining importers.

- * Native date input that hints the active locale via `lang=`. Browsers
- * use this hint to render the calendar widget in dd.MM.yyyy / MM/dd/yyyy
- * order, which is the user-visible format we want to follow the app's
- * EN/DE preference. Wrapping the prop here keeps every callsite from
- * having to pull `locale` out of `useTranslations()` just to feed it
- * back into the same JSX prop, and guarantees a future date input
- * cannot silently regress by forgetting the hint.
- *
- * v1.4.33 — height parity with `<Input>` and `<NativeSelect>`.
- *
- *   Mobile Safari + Android Chrome give `type="date"` (and
- *   `type="datetime-local"`) an intrinsic chrome that puffs the
- *   field past Tailwind's `h-10`, so the DOB cell on
- *   `/settings/account` rendered ~6 px taller than its row siblings
- *   and roughly 12 px wider on the Pixel-5 mobile-pass screenshots.
- *   `appearance-none` switches the native widget off, then
- *   `min-h-10` re-asserts the contract that every other input
- *   primitive ships. The `:webkit-date-and-time-value` shadow rule
- *   forces the embedded value text to occupy at least one full line
- *   even when iOS shrinks its placeholder, so the field looks
- *   identical on both engines.
