Add regression test for custom template defaults (#747)

The hardcoded height/width fallbacks (540/720) in cmd/init.js were
removed during the v2 refactor. Add a test that passes the old
hardcoded values in defaults and verifies that template defaults
(1080/800) take precedence, preventing the original regression.
