Traefik matches hosts exactly, so an app serving a wildcard domain under the `traefik` ingress class had a valid certificate but silently 404d on every request. Wildcard domains now render as a `HostRegexp` rule that matches a single label, the same semantics as a Kubernetes wildcard host, so both ingress classes behave the same. Those routes carry an explicit low priority so an exact domain on any app still wins over another app's wildcard, mirroring ingress-nginx.
Adds four Go template tests for ingress-route.yaml covering the imported-cert secret name, multiple domains per IngressRoute, the non-traefik ingress_class guard, and the https port_map dedup when an http port_map already covers the same container port. Also adds a bats integration test that deploys a TLS-enabled app under traefik and asserts both IngressRoute manifests and live http-to-https redirect plus https serving.
