[IMP] purchase(_stock): portal update scheduled date

1. Show only date not datetime on update portal. When update the
scheduled date, set it to be the last minute of that date.
2. Send updated date immediately when user pick a date.
3. If an activity for update the date already exist, update the
note instead of creating a new one.
