Wait for notification-templates request in debug trigger

Editor assessment

The subject is a precise, imperative statement of a test-stability fix: the debug-trigger flow now waits for the notification-templates request, under an accurate cypress scope. A reader familiar with flaky tests understands exactly what changed and why it is desirable, timing synchronization, without opening the diff, which satisfies the standard for a contained change with no body. No footers, none needed. Hygiene is clean: no trailing period, no junk, sensible length. A small, exact, publishable message for test-infrastructure work. That completeness is what keeps it publishable.
