Openwrt and Hetzner DDNS

@Christopher Obbard - I saw that you were comitting changes to #openwrt in Feb to include #Hetzner as a #DDNS option. I posted this in the Openwrt Forum but ...

@abeorch hi, with latest openwrt stable it just works, you can choose hetzner cloud as an option :-)
@obbardc So that's 25.12.1? - That would be great. I'll be putting into my test machine as soon as I get home then.
@abeorch yeah, I'm running 25.12 and it works out of the box!
@obbardc Thanks for your work.
@abeorch hah, the story was I was running some Docker container on my openwrt router to update some Hetzner DDNS zones. Thought it was really inefficient to have a complete docker stack on the router just for that purpose, so hacked up a quick script and created a PR to integrate Hetzner into ddns-scripts package! Glad someone other than me is using my work. Let me know if you get it working or not.

@obbardc Well I'm home.. I've got my test harness updated with #Openwrt 25.12.1 and its running (so the scripts etc on openwrt are all looking good - but - oh yeah you actually need to move the zone file to the cloud API right.. Ops. No problem - unless of course you are right in the middle of a #brownout during the #hetznerdnsapi shutdown..

This does actually point to another issue. I'm going to have to move all devices that use same zone file at the same time. (Obvious in retrospect) - Luckily I run a few domains so I can test a bit with one first.
