Minor technical improvements.

The daily summary counted only part of the day • The evening takings summary now covers the whole day. Payments settled before their booking was due were missing from it, and because the figure in a notification is never recalculated, they never showed up at all. • Notifications and widgets now refresh when a payment is entered on another device. Until now your phone did not know about it until you changed something on it yourself. • Booking reminders show the time the way your language writes it. In English they said "at 14:30". • The number pad in the checkout closes with Done. It used to sit over the change due and over the Cash and QR buttons. • Filled in English text in the places that were still showing Czech.

iCloud sync fix • Your data now actually syncs between devices. In the previous version it was only ever stored on the device and never reached iCloud. • If you are signed in to iCloud, everything you have recorded so far uploads automatically after the update — nothing to do by hand, and nothing is lost. • Settings now shows the real reason under Last sync when syncing fails (a signed-out iCloud account, no connection, and so on) instead of a generic message. • The Sync now button no longer reports a failure when everything is simply already up to date.
