fix: match date/time picker style, fix two-row footer layout

- Replace Modal.Footer with plain div to avoid bits-ui class merging (sm:flex-row override)
- DatePicker wrapped in flex items-center justify-center matching BookingCreateModal
- Time picker uses Button elements with fuchsia selection (hover:bg-fuchsia-50, bg-fuchsia-100)
- Generate 30-min time slots from 08:00-18:00 matching salon hours
- Reschedule form container uses bg-gray-50 matching other sections
- Footer: two rows with flex-1 buttons for equal width
