Subject: [PATCH] arr: declare critical config.xml elements via configXml

Pin <Port>, <BindAddress>, and <EnableSsl> in each arr service's
config.xml through arr-init's new configXml option. A preStart hook
ensures these elements exist before the service reads its config,
fixing the recurring Prowlarr bug where <Port> was absent from
config.xml and the service would run without binding any socket.

Updates arr-init lock to 6dde2a3.
