Shipped in v0.158.0, caught live within the hour. /apps/<slug> returned 500
for EVERY app: html/template cannot call a pointer-receiver method on a
non-addressable value, and appDetailHandler passes Meta as a VALUE inside a
map[string]interface{}.
It compiled and every test passed because nothing rendered app_info - the
catalog tests used the funcmap route, which takes a value and works either
way. A template method call is only checked when the template runs.
Adds TestAppInfoRendersForEveryLifecycle with the handler's exact data shape.
