ingress-nginx is gone and every app is served by the Envoy Gateway. The certificates were created by cert-manager's ingress-shim and are owned by the Ingresses, so each app now declares its Certificate itself, with the same name, secret and usages, so nothing gets reissued. gateway-shim can't take over because the certificates live in the app namespaces.
immich drops mbg.hensen.io, which has no route, so that one certificate is reissued through the Gateway's HTTP-01 solver.
Also removes the Longhorn test-port redirect URI and updates comments that still described nginx.
Longhorn has no users of its own; nginx guarded it with basic auth using apr1 hashes, which Envoy Gateway does not support. An Envoy Gateway SecurityPolicy now sends visitors through an authentik OIDC application that only admins may use. The client secret lives in Vault at kv/longhorn-oidc and reaches both authentik and Envoy through External Secrets.
