Two fixes uncovered while wiring up the first new Traefik route
(hall-of-presidents.local.mk-labs.cloud for honcho):
* traefik_host changed from 10.1.71.35 -> lightning-lane.local.mk-labs.cloud
so wed/.ssh/config rules (Host *.local.mk-labs.cloud) match and the
rsync step uses the right IdentityFile.
* requirements.yml: pin effectivelywild.technitium_dns >=1.1.0 — the
playbook depends on it but the collection was not declared. Bare
checkouts would fail without it being installed manually.
