test(installer): tie each platform source flag to its own value

Both secrets were only ever set together, so a cert flag keyed on
platformSourceSecret stayed green. A pull-through cache behind a private
CA usually needs the CA without credentials, which is exactly the case
such a slip breaks. The absence checks match the flag by prefix, since
a whole-element comparison misses the flag rendered with any value.
