openthread-border-router: 0-unstable-2025-06-12 -> 2026.06.0

[JamieMagee]

Updates ot-br-posix to the 2026.06.0 release. Switches the mDNS backend to OpenThread's built-in publisher, since OTBR_MDNS=avahi was removed upstream. avahi and the netfilter inputs are dropped, and the NixOS module no longer enables avahi.

This makes it work

[NyCodeGHG]

Home Assistant also can no longer find the Border Router after this update.

Caused by something else, ignore please

[NyCodeGHG]

do we still need this?

[JamieMagee]

Looks like no. I've removed it in the latest push.

[JamieMagee]

Thanks for the tips about OTBR_VENDOR_NAME and OTBR_PRODUCT_NAME. I've added them, as well as a comment explaining why they are needed.
