Delivery countdown in Hungarian (Kifli.hu) #102

Help us show the live delivery countdown for Kifli.hu users.

In the last few minutes before delivery, the shop usually shows a countdown like "kb. 2 perc múlva". The integration only understands the Czech version so far. To add Hungarian, we need to see the real message, and we can't get it from outside Czechia.

If you order from Kifli.hu, you can help in two minutes: 🙌

1. After a delivery, open the Delivery Info sensor in Home Assistant and look at its history.
2. Copy the last few messages, especially the final one before the courier arrived, into a comment here.
3. Remove anything personal (name, address, phone number) first.

It also helps to see a message with a date in it (e.g. for a delivery on another day). Hungarian usually writes the month first, and we want to read it correctly.

Optional: a diagnostics file downloaded while a delivery is on its way (Settings → Devices & Services → Rohlík.cz → ⋮ → Download diagnostics) shows the original formatting. Personal data is removed automatically, but please check the file before attaching it.

Comfortable with Python? A pull request extending _MINUTES_UNTIL_PATTERN in utils.py, with a test using a real message, is welcome too.
