/// Task 24: the template editor exposes a Native Alarm Sources subsection (a new
/// tab) for authoring read-only native alarm bindings. <c>TemplateEdit</c> is a
/// heavyweight page (~10 injected services with their own graphs); like the other
/// TemplateEdit coverage in this suite (see <c>TestRunWarningTests</c>), these are
/// structural assertions over the component source that pin the subsection's
/// wiring — the tab, the authoring form (connection dropdown, source reference,
/// filter, lock), and the repository-direct CRUD calls — so it cannot silently
/// regress. The CRUD behaviour itself is covered end-to-end by the ManagementActor
/// native-alarm-source handler tests.
