feat(frontend): jalali calendar + drop legacy moment-jalali

- Wire Calendar Type setting to a real Jalali datepicker via
  vue3-persian-datetime-picker, gated by useDatepicker composable
- DateTimePicker wrapper swaps between AD-Vue and Persian picker; keeps
  dayjs v-model contract so existing forms/setters work unchanged
- Theme picker popup explicitly per body.dark / data-theme=ultra-dark
  (AD-Vue 4 doesn't expose CSS vars, so var() fallbacks defaulted to
  white); fix invisible disabled days, SVG arrow fills, popup clipping
  via append-to="body"
- Replace stray moment() calls in dbinbound/inbound models with dayjs;
  the legacy global was undefined under ESM and broke the inbounds list
  whenever any inbound had expiryTime > 0
- Remove legacy moment-jalali / persian-datepicker / aPersianDatepicker
  assets — replaced by the Vue 3 picker

Note: dark/ultra background of the date popup still renders white in
some cases — pending follow-up.
